Patient's question:
I am 24 years old. I am currently pregnant and have not had a period for a while. I don't know why this is happening. Why haven't I had a period? What could be the reason? I would like to learn more about it.Doctor's answer:
Hello, according to your description, menstruation is caused by the estrogen and progesterone levels in the body reaching a certain level. After the ovaries cease to function, the sudden rise in hormone levels leads to the shedding of the endometrium, resulting in vaginal bleeding. When pregnancy occurs, the egg released from the ovary fuses with sperm, stimulating the corpus luteum to secrete estrogen and progesterone, which helps the embryo grow and develop. At the same time, the body also secretes human chorionic gonadotropin (hCG). Therefore, without the process of rising estrogen and progesterone levels, it will not cause the shedding of the endometrium. After becoming pregnant, menstruation does not occur.
