Patient's question:
Menstruation is delayed, there was sexual intercourse during the period, but there was no ejaculation inside, is the chance of pregnancy high?Doctor's answer:
Hello, you might be pregnant. You can go to the hospital to check blood hCG to confirm. Withdrawal contraception may fail, as some sperm may come out before you feel like you're about to ejaculate. The failure rate can be as high as over half.
