This past cycle my period was 8 days late according to my calculations and i started showing pregnancy symptoms, so i took a test last monday and it was faint positive, so i took another test 3 days later and it was negative, then my period started friday. I usually have pretty heavy flow the first 2 -3 days and really bad cramps, this time i had really light bleeding with cramps and now 2 days later my period has stopped and i still have cramps. i had unprotected sex around the time i should have ovulated.
