Patient's question:
Can sexual intercourse after menstruation lead to pregnancy?Doctor's answer:
The safe period generally refers to the 7 days before the onset of menstruation and the 8 days after it ends. Intercourse during the safe period usually does not lead to pregnancy. With an ultrasound, it can generally be determined around 20 to 35 days. If using a urine test, the earliest it can detect pregnancy is 10 days after intercourse with a pregnancy test kit.
