Pregnancy test strips showed pregnancy. What's going on? Medical history and treatment effects: Ultrasound said everything was normal. What kind of help do you want: Is it possible to have a miscarriage?Doctor's answer:
In general, pregnancy usually does not result in menstruation. If menstruation occurs during pregnancy, it is not pregnancy. If you experience menstruation after becoming pregnant and the flow is very heavy, it could be caused by conditions such as miscarriage, ectopic pregnancy, or cervical erosion, leading to vaginal bleeding. It is best to seek medical attention promptly to determine the cause. In fact, vaginal bleeding in the early stages of pregnancy is not true menstruation; it may also indicate issues with the cervix. However, in very rare cases, pregnancy menstruation can be understood as a physiological response after the fertilized egg implants. Menstruation after pregnancy is implantation bleeding that occurs after the fertilized egg attaches. In the early stages of pregnancy, after the egg is fertilized and implants, human chorionic gonadotropin (hCG) begins to appear in the urine, reaching its peak at the 8th week of pregnancy. This hormone's function is similar to luteinizing hormone, promoting the development of the ovarian corpus luteum into the corpus luteum of pregnancy. The corpus luteum continues to secrete estrogen and progesterone, transforming the endometrium into the decidua to ensure the continued growth and development of the fertilized egg.
