As we all know, menstruation will stop naturally after pregnancy. However, there are also some women who are obviously pregnant, but their aunts still come to greet them \”as promised\”. For expectant mothers in the first trimester, it can be really shocking and scary. Is this abnormal or normal? Is it a false alarm or an ominous sign?
1. Will I still have my period when I am pregnant?
I saw red when I was pregnant and it scared me to death
Lin Chen has been married for two years and has always wanted a child. In April this year, she finally became pregnant with a snake baby, and the whole family was immersed in joy. But when the baby was less than two months old, Lin Chen woke up one day and suddenly found blood on his underwear. This frightened and frightened her. Could seeing redness and swelling during pregnancy be a sign of miscarriage?
Everyone has an innate common sense concept: Under normal circumstances, the first manifestation of pregnancy is menopause. Married or sexually active women with regular menstrual cycles should consider the possibility of pregnancy if their menstruation is delayed. But this is not absolute.
It was a false alarm, it turned out to be my aunt reporting for duty
Lin Chen was very nervous, and the whole family was also worried. The family was shocked and rushed Lin Chen to the hospital for examination, but it turned out to be a false alarm. It turned out that the \”eldest aunt\” had already come to work. Lin Chen was overjoyed, but also very curious: I am pregnant, why am I still menstruating? This is different from normal female pregnancy.
The doctor explained: Usually menstruation will come on time every month, because ovulation occurs once every month, and the menstrual period is usually 3-5 days. During this period, the functional layer of the endometrium falls off, causing intrauterine wounds. The basal epithelial cells of the endometrium divide and proliferate every day, move to the ulcerated wound, and gradually repair and form a new functional layer. At this time, new egg cells in the ovary grow, mature, and ovulate, produce the corpus luteum, and produce sex hormones, which cause the endometrium to proliferate, peel off, and bleed again, so menstruation begins again. The ovaries discharge the ovaries once a month, thus forming a monthly menstruation.
If the egg is fertilized, the body will regulate the secretion of hormones to maintain the endometrium from shedding, which manifests as menopause. However, there are still several situations where dysmenorrhea may still occur during pregnancy.
2. Menstruation may also occur during pregnancy
Lin Chen\’s confusion is understandable, because usually, the first symptom of a woman\’s pregnancy is menopause. Married or sexually active women with regular menstrual cycles should consider the possibility of pregnancy if their menstruation is delayed. But this is not the absolute truth – it is still possible to \”get your period\” during pregnancy.
1. Reason 1: Unstable implantation of the fertilized egg
[General situation]: Menstruation is bleeding caused by necrosis and shedding of the endometrium after ovulation. In a sense, menstruation is the preparation of a woman\’s uterus for pregnancy. Under normal circumstances, the fertilized egg successfully implants in the endometrium, and the womanOvulation will not occur and this preparation is unnecessary, so menstruation will generally stop during pregnancy.
[Special circumstances]: Since the implantation of the fertilized egg is not yet stable and the placenta has not yet formed, mature eggs are still released when approaching or reaching the menstrual date and are expelled from the body along with the shedding of the endometrium. Therefore, a small number of pregnant women think that it is \”menstruation\”. .
2. Reason 2: Endometrial shedding
[General situation]: After a woman becomes pregnant, her ovaries will secrete a large amount of progesterone and estrogen to promote the thickening of the endometrium, thus providing fertile \”soil\” for the implantation and growth of fertilized eggs. At this time, due to the increasing levels of estrogen and progesterone in the woman\’s body, the endometrium will no longer shed, and the woman will no longer have menstruation.
[Special circumstances]: Due to individual differences and other reasons, the levels of sex hormones, especially progesterone, secreted by the ovaries of some women after pregnancy are low, causing a small part of the endometrium to continue to shed. Therefore, these women will still have menstruation after pregnancy, but the amount will be much less than normal. After three months of pregnancy, the placenta forms and estrogen and progesterone remain at high levels in the female body. At this time, the endometrium will no longer shed and menstruation will not come.
Warm reminder: Be wary of threatened abortion or ectopic pregnancy
In the early stages of pregnancy, if vaginal bleeding may be caused by the above two reasons, it is a false alarm. However, it should be noted that vaginal bleeding may also be caused by abnormalities such as threatened miscarriage or ectopic pregnancy.
Women with threatened miscarriage and ectopic pregnancy will also experience vaginal bleeding in the early stages of pregnancy, which can easily be mistaken for normal menstruation. However, vaginal bleeding in women with threatened abortion and ectopic pregnancy is usually not related to the menstrual cycle and is mostly continuous bleeding. Patients are often accompanied by symptoms such as abdominal pain and lower abdominal swelling.
If women of childbearing age encounter the above-mentioned vaginal bleeding, they must be diagnosed early, otherwise, the child may miscarry and the pregnant woman may also be at risk of bleeding to death.
