I had unprotected sex on July 1st. I started my period on July 13th but it was a bright pink spotting and only showed when I wiped. It lasted that way for 3 days and got heavy on the 4th day. I took a pregnancy test after my period and it was a very very faint positive. Every day after that I was cramping. Not as bad as my regular period cramps. I took another pregnancy test on August 6th and it came back positive again, still faint but a clearer positive line than the 1st test taken. On August 11th I started my period again but same thing happened. Very light pink spotting and only when I wipe. Today is the 12th and it's still light spotting. I still feel cramps but not as bad as a regular period cramping. I don't know if anyone has ever experienced this and ended up pregnant or could it be something more serious?
