Patient's question:
I had my period on November 30th and had sex around December 27th, but my period still hasn't come by January 3rd. What should I do?Doctor's answer:
Generally speaking, if menstruation lasts more than a week, you can determine pregnancy by testing urine HCG, also known as a home pregnancy test. In your case, you can start by testing a first-morning urine sample. If you are pregnant, it would be approximately 36 days into the pregnancy. If pregnancy is confirmed, you can have an ultrasound at around 40 days to check for a gestational sac and fetal buds in the uterine cavity.
