Patient's question:
Hello, there was sexual activity before the menstrual period, but there hasn't been any since then. However, this time, my period has been delayed for nearly ten days, and I don't think I'm pregnant! Thank you for your answer! I'm really frustrated! First follow-up question: There was sexual activity two or three days before the period, but most of the time it was withdrawal. After the period started, there hasn't been any sexual activity. I don't know what's going on.Doctor's answer:
Hello, having intercourse one week before or after your menstrual period is generally not likely to result in pregnancy because it falls within the safe period. The safe period is applicable to women with regular menstrual cycles (28 days), where ovulation typically occurs around 14 days before the next menstrual period. If the cycle shortens, this 14-day window also shortens. However, the safe period is not entirely foolproof, as the probability is relatively low. This is because many women with irregular menstrual cycles also have irregular ovulation patterns. Therefore, the safe period is not absolutely safe. You can wait about 10 days after intercourse to visit a hospital for a blood HCG test to check for pregnancy. This method is highly accurate. Alternatively, you can use a pregnancy test kit 14 days after intercourse to determine if you are pregnant.
