Will you have menstruation in the first month of pregnancy?

Pregnancy is the fusion of sperm and egg, which produces sperm and egg fusion, and then grows into a test tube embryo. Once the sperm and egg fusion is produced, it is not easy to accept the invasion of other sperm, it is not easy to ovulate again, and after pregnancy, estrogen and progesterone will increase significantly, and menstruation is not likely to come again.

However, some women still experience vaginal bleeding after pregnancy. This is not menstruation, but abnormal vaginal bleeding. Vaginal bleeding during early pregnancy is more common in the following situations:

(1) Ectopic pregnancy: Ectopic pregnancy refers to abnormalities in the process of embryo implantation after the combination of sperm and egg, resulting in unsuccessful embryo implantation. In clinical medicine, the hcg level shows pregnancy, but the standard value is low, the embryo does not double and grow, and the gestational sac cannot be seen on B-ultrasound. The result of ectopic pregnancy is menstruation. Some women initially detect pregnancy with a test paper, but then they "have their period" and the test paper is negative. This belongs to this situation.

(2) Threatened abortion: It is the most common cause of vaginal bleeding during early pregnancy. The amount of bleeding is generally not more than the menstrual volume, the hcg value is normally doubled, and B-ultrasound shows that the size of the test tube embryo is also growing regularly. In this case, bed rest and tocolysis treatment are sufficient.

(3) Embryonic arrest: The main manifestations are small amounts of vaginal bleeding. B-ultrasound shows that the test tube embryo is not growing and developing regularly, there is no fetal heartbeat, and hcg generally does not double or even shows a downward trend. Once embryonic arrest is diagnosed, abortion should be performed as soon as possible.

(4) Spontaneous abortion: The main symptoms are vaginal bleeding, heavy, equivalent to menstrual flow, accompanied by abdominal pain and discharge of pregnancy products. Once spontaneous abortion occurs, you should go to the hospital immediately to check whether the complete gestational sac has been discharged.

Generally speaking, it is not easy to have menstruation during pregnancy. Vaginal bleeding is more common in the above conditions. It should be diagnosed and treated accordingly!

Will I have my period in the first month of pregnancy?

Menstruation occurs every month when a woman is not pregnant. However, some women will still have their periods after they become pregnant, especially in the first month of pregnancy, when a large number of women will continue to have their periods. In fact, this is not a real period, it just looks like a period. So will menstruation still occur in the first month of pregnancy? How could this happen?

1. Will I continue to have my period during the first month of pregnancy?

After a woman becomes pregnant, her uterus and ovaries stop ovulating, and generally speaking, it is not easy for her to have her period again. However, there are very few women who still have their periods in the early stages of pregnancy. In the early stages of a woman's pregnancy, the body's estrogen levels are low, the formation of the uterine decidua is not yet complete, and the uterus and ovaries do not release complete eggs every month, so the uterus will continue to bleed regularly. This is why menstruation still occurs after pregnancy. However, since the embryo is gradually formed after the third month of pregnancy, the abnormal uterine bleeding stops, so the next menstruation during pregnancy is unlikely to exceed four months.

2. Why do I still have my period when I am pregnant?

Reason 1: Unstable embryo implantation

General production situation vaccine: Menstruation is the bleeding caused by the necrosis and shedding of the uterine wall after ovulation. To a certain extent, menstruation is the woman's uterus preparing for pregnancy. Under normal circumstances, if the sperm and egg combine successfully and the embryo implants into the uterine wall, the woman will not ovulate, and this kind of preparation is no longer necessary. Therefore, during pregnancy, the menstrual period will generally stop.

Special production circumstances vaccine: Because the embryo implantation is not stable, the embryo has not been formed, and it is close to or has arrived at the menstrual day, and a perfect egg cell will be discharged, and then fall out of the body along the uterine wall, which causes a small number of pregnant women to think that they are having their "menstrual period".

Reason 2: Uterine wall falls off

Production general condition vaccine: After a woman becomes pregnant, the ovaries will secrete a large amount of estrogen, female hormones, etc. to promote the thickening of the endometrium, thereby providing a rich "soil" for the embryo combined with sperm and egg to implant and grow. At this time, because the level of female hormones and estrogen in women's bodies continues to rise, the uterine wall will no longer fall off, and women will not easily have their periods again.

Production of special circumstances vaccine: Due to individual differences and other reasons, some women's uterus and ovaries secrete lower levels of estrogen, especially progesterone, after pregnancy, causing a small part of the uterine wall to continue to fall off. Therefore, these women will still have their periods after pregnancy, but the amount of menstruation will be much less than the normal stage. Until three months after pregnancy, the embryo is produced, and the female hormones and estrogen in the woman's body remain at a relatively high level. At this time, the uterine wall no longer falls off, and the menstrual period no longer comes.
