I had sex 4 days before I started my period, and my period only lasted 2 days and it stopped, could I be pregnant? My period usually lasts 7days

Your . Your bleeding could be dysfunctional uterine bleeding, from irregular hormones, or it is possible that you could be pregnant. Some pregnancies cause "spotting", or irregular bleeding. Please take a pregnancy test to be sure. If you developed heavy bleeding, vomiting, light-headedness, or faint, then you must be seen as an emergency.
