Patient's question:
On January 5th, menstrual cycle of 40 days? On February 2nd, black-brown discharge has already started, and then menstrual blood came for three or four days. Is this considered menstruation... Had sexual intercourse on February 1st, on February 10th (9 days after intercourse) hCG 0.1... On February 13th, ultrasound showed endometrium 0.2 cm, otherwise normal... On February 17th (16 days after intercourse) re-examined hCG 0.1, is it normal?Doctor's answer:
A normal menstrual cycle for women is once a month. During the menstrual period, dark brown discharge may appear again from the lower body, with a small amount, which is inconsistent with regular menstruation. This should be considered as menstrual irregularity. From the perspective of blood HCG levels, pregnancy has not occurred. When the endometrium exceeds 1.0-1.2 CM, menstruation will occur. However, the current endometrium is 0.2 CM, which is the thickness during the menstrual period. Therefore, this bleeding should be considered as menstruation, but due to the small amount, menstrual irregularity should be considered. According to the estimation of the 2nd menstrual period, coitus occurred on the 17th, which is the ovulation period.
