So my bc and I had sex on April 27th . According to my p tracker app , that was the day before I ovulated . I was suppose to get my period on May 16th but I got it 4 days early (May 12th) it was lighter than usual , I had cramping the first day . Slight bleeding (only one pad a day) for 2 and 1/2 days then I began to spot brownish blood . Then this month I got my period 2 days late . And it only lasted 3 days And most of it was brown discharge . I haven't noticed any symptoms aside from being really tired . But do you think I could be pregnant ?
