I had unprotected sex during my fertile window and this month I had a very unusual period it only lasted three days and a bit of spotting on the forth day. My period usually lasts a firm 7 days! Could this be a major sign of pregnancy? My boyfriend says that I am, but I don’t believe I am. Is there a possibility that I’m pregnant is it too early to test ???? Plz help.

Edit: Has this happened to anyone before and it turned out you were indeed pregnant? 😬😬
