Implantation cramping may be an early sign of pregnancy. Understanding the differences between early pregnancy cramps and period cramps will help people to recognize them.
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
Implantation cramps are not the same as period or menstrual cramps.
Menstrual cramps happen during a period, which occurs approximately once every 28 days, so long as there is no pregnancy.
Menstrual cramps happen when the uterus contracts to expel its lining.
Substances called prostaglandins trigger the uterine muscles to contract.
Prostaglandins are associated with pain and inflammation. This process may cause cramping.
Not everyone gets implantation cramps and bleeding when they first become pregnant.
28 percent of those who had spotting and light bleeding also reported pain. 54 percent of those with heavy bleeding also experienced pain.
Not everyone has cramps during implantation. And for those that do, the cramps may be mild or moderate.
Some people describe the sensation as:
- tingling feeling
This can help differentiate it from a menstrual cramp.
It is unusual to have intense cramping pain during implantation, so anyone who experiences painful cramping between periods should be assessed by a doctor.
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. This is called implantation bleeding and is lighter than a regular period.
Implantation cramping or bleeding may be an early sign of pregnancy.
It is easy to mistake period cramping or a light period for symptoms of implantation.
Because of the similarity of symptoms between menstruation and implantation, it helps to know the other early signs of pregnancy.
Other early signs of pregnancy
If someone thinks they are pregnant, it is a good idea to take a home pregnancy test. A good time to do this is 1 to 2 weeks after noticing the early signs of pregnancy.
If a fertilized egg has implanted into the uterus wall, the body will already have started to form the placenta. In this situation, the pregnancy hormone, human chorionic gonadotropin (hCG), begins to rise.
If the pregnancy test is positive, the next step is to make an appointment with a doctor. The doctor can confirm whether the home test is correct.
Anyone who already knows they are pregnant and is experiencing heavy bleeding or cramping should speak to a doctor. These symptoms may indicate a problem with the pregnancy.
Sometimes, individuals who are not pregnant may experience painful cramping or bleeding in between periods. If this occurs, it is a good idea to discuss the issue with a doctor.
