Implantation cramping is a type of pain sometimes experienced when a fertilized egg attaches itself to the lining of the uterus. This process is called implantation. Cramping sometimes occurs when this happens, but it does not always cause pain. Anyone experiencing implantation cramps should avoid taking some anti-inflammatory medications, such as aspirin.
This is because taking anti-inflammatory medicines around the time of conception might increase the risk of miscarriage, according to a study. Menstrual cramps happen during a period, which occurs approximately once every 28 days, so long as there is no pregnancy. Prostaglandins are associated with pain and inflammation. This process may cause cramping. One-quarter of participants in a study reported bleeding in their first trimester.
Only 8 percent of those had heavy bleeding. Not everyone has cramps during implantation. And for those that do, the cramps may be mild or moderate. It is unusual to have intense cramping pain during implantation, so anyone who experiences painful cramping between periods should be assessed by a doctor.
Implantation tends to happen 6 to 12 days after ovulation when pregnancy occurs. This is about the same time that a person would usually expect a period to start.
If an egg has been fertilized, the body prepares the uterus lining to receive and protect the egg. Some light bleeding or spotting may accompany implantation cramping. While many women experience breast swelling or tenderness before their periods, this is likely to be more noticeable than usual in very early pregnancy. Increased levels of progesterone following implantation can make you feel nauseous. But again, this most commonly occurs around 4 or 5 weeks of pregnancy about the time you miss your period.
Progesterone slows down your digestion, which can contribute to nausea. Rising hCG levels and a more sensitive sense of smell can make the problem worse — so now might be a good time to avoid cooking liver and onions. Find yourself content and happy one minute, and weeping at a commercial on TV the next?
Or excited to see your partner in the evening and then biting their head off over nothing? You may be experiencing mood swings. Estrogen and progesterone, as well as hCG, increase very quickly following implantation.
If you get pregnant, your temperature remains elevated. Some women seem to experience a one-day drop in temperature around the time of implantation. This is different than the drop in temperature that means your period is coming — in the case of an imminent period, your temperature would stay low.
In the case of implantation dip, your temp drops for one day and then goes back up. According to an analysis of more than , BBT charts from the popular app Fertility Friend, 75 percent of pregnant women using the app did not experience an implantation dip. Additionally, a dip was noted on approximately 11 percent of the charts of women who were not pregnant.
We wish it were — when will researchers get on this? But it may be helpful when it comes to interpreting your BBT chart. Trying to get pregnant can be both an exciting and nerve-wracking time.
Some women do notice signs and symptoms that implantation has occurred. So-called implantation bleeding will likely arrive earlier than your expected monthly menstrual period, usually around seven to 10 days after fertilization or conception.
Since implantation bleeding is a symptom that can often occur before you test positive on a pregnancy test, it can be hard to know whether light bleeding is an early sign of pregnancy or just normal spotting leading up to your period. The timing of when you last had sex might also help you figure it out. About a third of women who report having experienced implantation bleeding often describe it as distinct from their usual premenstrual spotting — some say the blood is darker and not as red compared with normal period blood.
Others have mild cramping at the same time as the spotting. Light bleeding during pregnancy — even at times other than implantation — is often normal. Causes can include mundane things like irritation of the cervix following a pelvic exam, sex or infection of the vagina.
