While symptoms like nausea and fatigue are commonly associated with the early stages of pregnancy, cramps might seem more indicative of your period approaching. However, this isn’t always the case.
Some women describe feeling the moment a fertilized egg implants into the uterine lining. This process, known medically as implantation, marks the beginning of pregnancy. But is implantation cramping a real phenomenon? If so, could it be among the very earliest signs of pregnancy? Crucially, where do you feel implantation cramps, and what do these sensations actually feel like? Let’s explore these questions.
Key takeaways
- Implantation cramps are considered mild and are believed to occur as the fertilized egg embeds into the uterine lining.
- These cramps are typically felt in the lower abdomen, around the pubic bone area.
- Implantation cramps are generally short-lived, lasting from a few hours to a couple of days.
- It’s easy to confuse implantation cramps with PMS or other early pregnancy discomforts.
- If you suspect pregnancy, wait until you’ve missed your period to take a pregnancy test for accurate results.

What are implantation cramps?
Before we delve into the specifics of where do you feel implantation cramps, let’s recap what implantation itself entails.
Each menstrual cycle, one of your ovaries releases an egg, a process called ovulation. In a typical 28-day cycle, ovulation occurs around day 14. Using a cycle tracking app like Flo can help you pinpoint when ovulation is likely to occur for you. Once released, an egg is viable for fertilization for up to 24 hours. Conception happens if sperm fertilizes the egg during this window.
Following fertilization, the egg journeys through a fallopian tube and then attaches itself to the uterine lining, preparing to grow into an embryo. This attachment process is implantation, and it generally takes around six to ten days after ovulation.

Your body prepares extensively for implantation each cycle. Progesterone, a key hormone, is released to thicken and enrich the uterine lining with blood vessels. This thickened lining provides the ideal environment for the fertilized egg to attach securely.
In approximately 25% of pregnancies, the embedding of the fertilized egg can cause a minor disruption of these blood vessels, resulting in what we call implantation bleeding.
Concurrently, some women report experiencing implantation cramps. However, these sensations aren’t universally noticed due to the significant hormonal and physiological shifts occurring in early pregnancy. Is there a connection between implantation cramps and bleeding?
“Mild cramping in early pregnancy is indeed very common,” notes Dr. Jennifer Boyle, an obstetrician and gynecologist at Massachusetts General Hospital. “The precise cause of this cramping sensation remains unclear. The implanted fertilized egg is incredibly tiny – much smaller than 1 mm in diameter. Due to its minute size, it’s unlikely to directly cause noticeable symptoms during implantation. Early pregnancy cramping is more likely attributed to hormonal fluctuations and the uterus beginning to expand.”
Because implantation typically occurs around six to ten days post-ovulation, any bleeding or cramping you experience might coincide with your expected period, leading to confusion. At this early stage, confirming pregnancy is difficult, even if you are actively trying to conceive. It’s completely understandable to overlook these subtle signs, mistake them for an early period, or not experience them at all.
When do pregnancy cramps start?
Now that we understand that cramps are common in early pregnancy, potentially stemming from implantation or uterine growth to accommodate the developing baby, the question arises: when do these cramps typically begin?
This is a complex question as every pregnancy is unique. However, generally, implantation cramps can occur as early as ten days after ovulation. Alternatively, some women may start noticing early pregnancy symptoms within the first few weeks following conception.
“Cramping directly related to implantation would be very brief, lasting at most for one to two days,” clarifies Dr. Boyle. “However, cramping in early pregnancy more broadly is common and can persist throughout the first eight to twelve weeks.”
When trying to conceive, it’s natural to analyze every bodily sensation, wondering if it could be a pregnancy sign. This is perfectly normal. It’s important to remember that pregnancy symptoms can vary significantly from person to person and even between different pregnancies in the same person.
Not experiencing cramps doesn’t rule out implantation. The definitive way to confirm pregnancy is to wait for a missed period and take a pregnancy test.
What does implantation cramping feel like?
Since implantation often happens around the time of your expected period, it’s easy to mistake implantation cramps and bleeding for the onset of menstruation. However, Dr. Boyle highlights key differences that may help distinguish PMS cramps from implantation discomfort.
She explains that implantation cramping is typically much milder than period cramps. “Where do you feel implantation cramps?”, you might ask. “It’s usually felt just above the pubic bone, in the central lower abdomen,” she says. To locate this area, you can press gently on the lower part of your belly, towards your genital area.
How long do implantation cramps last?
Pinpointing the duration of implantation cramps is challenging due to limited scientific data. However, as Dr. Flanagan explains, “Typically, implantation cramps are very mild, and women might experience them for a day or two.”
“However, it’s important to note that some individuals experience cramping throughout early pregnancy for several days. This is more likely due to hormonal fluctuations rather than the physical act of implantation itself.”
Tracking any unusual pain or cramping, including the timing and nature of the discomfort (using an app like Flo can be helpful), can provide valuable information. This record can assist in retrospectively differentiating between potential implantation cramps and other causes of discomfort.

“Implantation cramps are typically distinct from menstrual cramps in their pattern,” Dr. Boyle adds. “Menstrual cramps tend to intensify and then subside completely, while normal early pregnancy cramping is more likely to come and go, remaining consistently mild rather than escalating in intensity.”
Navigating the uncertainty of cramps – whether they are cycle-related, pregnancy-related, or due to something else – can be frustrating. If you have concerns about your symptoms, consulting your doctor is always a good step. If your cramps are indeed related to implantation, it may be too early to confirm pregnancy, but your doctor can assess your overall symptoms and advise on the next steps.
Other early pregnancy signs
While implantation cramps are not considered a common early sign of pregnancy due to the anecdotal nature of much of the information, if you suspect pregnancy, there are other signs and symptoms to be aware of, including:
- Missed period
- Nausea and vomiting
- Fatigue
- Breast tenderness
- Increased urination frequency
- Heightened sensitivity to smells, taste changes, and food cravings
- Mood swings
- Bloating
- Light spotting (implantation bleeding)
- Constipation
- Headaches
This list may seem extensive, and not all of these signs are pleasant. However, noticing a cluster of these symptoms could suggest pregnancy, and taking a pregnancy test might be advisable. You can also track your symptoms using the Flo app to provide detailed information to your doctor about your experience and symptom onset.
What else could be causing cramping?
Pregnancy triggers significant bodily changes. Hormonal fluctuations to support both you and your growing baby can lead to various unusual and sometimes uncomfortable symptoms, both physically and emotionally.
While some experience cramping during implantation, it’s not the only time you might feel aches or discomfort. In the initial weeks of pregnancy, you may feel your uterus stretching as it prepares for the baby’s growth. Gas and constipation are also common in early pregnancy. Similarly, bloating can cause discomfort, and nausea can make your abdomen feel sensitive.
Generally, cramping during pregnancy should be mild and temporary. If you are concerned about any discomfort, especially if it’s persistent or severe, consulting your doctor is recommended.
Tips for relieving cramps at home
Even though cramps are a normal part of early pregnancy, you don’t have to simply endure them. Pregnancy is a period of significant physical and emotional adjustments, and prioritizing your comfort is important. Dr. Boyle suggests these at-home remedies for cramps that don’t subside on their own:
Applying gentle heat with a compress can be a comforting method for easing mild implantation or early pregnancy cramps.
- Apply heat: A warm compress can offer soothing relief.
- Engage in light exercise: If feasible, gentle activities like yoga or walking may help alleviate cramps.
- Consider over-the-counter pain relief: Over-the-counter pain medications can provide relief. However, always consult your doctor before taking any new medication during pregnancy to ensure it’s safe for you.
When to take a pregnancy test
If you are trying to conceive and have experienced cramping, wanting to know if you are pregnant is natural.
However, it is still advisable to wait until the first day of your missed period before taking a pregnancy test. While this might be challenging, there is a good reason for this recommendation.
After implantation, your body begins producing human chorionic gonadotropin (hCG), the hormone detected by pregnancy tests in urine. hCG levels are initially very low in early pregnancy and increase dramatically during the first trimester. Testing too early increases the risk of a false negative result. By the first day of a missed period, hCG levels should be sufficiently high for accurate detection by a home pregnancy test.
More FAQs about implantation cramps
Are implantation cramps on one side or both?
“Early implantation cramping, or general early pregnancy cramping, is typically felt in the midline of the lower abdomen or pelvis, just above the pubic bone,” Dr. Boyle clarifies. However, individual experiences with implantation cramps vary, so slight differences in sensation are normal.
How many days after implantation are you pregnant?
Implantation officially marks the beginning of pregnancy. However, at this very early stage, pregnancy may not be detectable by a standard home urine test. These tests detect the pregnancy hormone hCG, which starts at low levels and rises throughout the first trimester. Waiting until the first day of a missed period is recommended for pregnancy testing to ensure hCG levels are high enough for accurate detection.
Are quick, sharp pains normal in early pregnancy?
“Quick, sharp pains are indeed normal during pregnancy,” Dr. Boyle explains. “The ligaments connecting the uterus to the body sides stretch significantly in early pregnancy as the uterus grows rapidly. Sudden movements or actions like coughing can cause these ligaments to pull, resulting in brief, sharp pains.” Nevertheless, any pain during pregnancy should be evaluated by a doctor to rule out any complications.
