Does having your period prove you are not pregnant?

As we all know, if a woman's menstruation does not come on time or is delayed, it may be due to pregnancy. However, in addition to pregnancy, there are many other factors, such as irregular menstruation and gynecological diseases. Female friends should first use an early pregnancy test strip to test for pregnancy. If there are symptoms of pregnancy, then you need to relax and fulfill your responsibilities as a mother. If there are other reasons, they need to be adjusted in time.

Does having a period prove that you are not pregnant?

People usually have an inherent common sense concept: Generally speaking, the first sign of a woman's pregnancy is amenorrhea. A married or sexually active woman with a regular menstrual cycle will think about the possibility of pregnancy if her menstruation is delayed. But this is not absolute.

1. Reason 1: Unstable implantation of fertilized egg

Generally speaking: Menstruation is bleeding caused by the necrosis and shedding of the endometrium after ovulation. In a sense, menstruation is the female uterus preparing for pregnancy. Under normal circumstances, if the fertilized egg successfully implants into the endometrium, the woman will not ovulate, and this kind of preparation will no longer be necessary. Therefore, menstruation will generally stop during pregnancy.

Special circumstances: Because the fertilized egg implantation is not stable, the placenta has not formed, and it is close to or on the day of menstruation, a mature egg will still be discharged and then discharged from the body along with the shedding of the endometrium, causing a small number of pregnant women to think they are having their "menstruation".

2. Reason 2: Endometrial shedding

Generally speaking: After a woman becomes pregnant, her ovaries will secrete a large amount of progesterone, estrogen, etc. to promote the thickening of the endometrium, thereby providing a fertile "soil" for the implantation and growth of the fertilized egg. At this time, as the levels of estrogen and progesterone in women's bodies continue to increase, the endometrium will no longer shed, and women will no longer have menstruation.

Special circumstances: Due to individual differences and other reasons, some women's ovaries secrete relatively low levels of sex hormones, especially progesterone, after pregnancy, causing a small part of the endometrium to continue to shed. Therefore, these women will still have menstruation after pregnancy, but the amount of menstruation will be much less than normal. It is not until three months into pregnancy that the placenta is formed and the estrogen and progesterone levels in the female body are maintained at a relatively high level. At this time, the endometrium no longer sheds and menstruation no longer occurs.

If you are sure that your menstruation is normal, you will definitely not be pregnant. However, some people may mistake abnormal vaginal bleeding for menstruation, which may not be the case. You can check the blood hcg for identification
