Patient's question:
I got my period last month by taking progesterone prescribed by a doctor. At that time, my endometrium was only about 3.5 mm, which is quite thin. After my period came on the 21st of last month and lasted for a week, I had intercourse during ovulation with withdrawal ejaculation. What is the chance of getting pregnant? Should I take birth control pills?Doctor's answer:
Irregular menstrual cycles make it impossible to estimate ovulation and safe periods. In such cases, coitus interruptus (withdrawal) combined with breastfeeding is not safe, so pregnancy is possible, although the chances are relatively low. Unless you can confirm that no semen was released during intercourse, pregnancy is still possible. If you are unsure, it is recommended to take emergency contraception as soon as possible. The earlier you take it, the better the effect. The latest time to take it is within 72 hours after intercourse.
