Can a small amount of menstrual flow affect pregnancy?

Patient's question:

I have very little menstrual flow, and I'm very worried about when my ovulation period is, since my husband smokes. Does it affect pregnancy? How long without pregnancy is considered abnormal?

Doctor's answer:

Under normal circumstances, the amount of menstrual bleeding is approximately 60 milliliters, with bleeding less than 30 milliliters being considered too little and more than 80 milliliters being excessive. Generally, low menstrual blood volume is due to low estrogen levels or underdeveloped uterine development. Hormones can stimulate the fibrosis and thickening of the endometrium to prepare for delivery.
Advice: If not yet pregnant, the fibrotic endometrium will shed and peel off to form menstruation. Low estrogen levels can cause the endometrium to grow insufficiently thick, resulting in less peeling during menstruation. This condition may later affect delivery. We recommend you visit a hospital to identify the cause and receive targeted treatment! Gynecological diseases are a common gynecological condition, and during medication, women need to pay attention to their self-care.
