So my boyfriend and I had sex just about every day that I was ovulating and we did not use any form of birth control. According to my period schedule which is never off I was supposed to start today. I usually always get my periods in the morning but today nothing not even a cramp. I decided to take a test just to see and it came back with a faint line. The box says two lines mean pregnant but it doesn’t say anything about a faint line. What could this mean?
