i already had my period for this month, my period last up to seven days on the 5th days i had intercourse which stopped my period i spotted for one day after my period and that was it, so i think i stopped it before its seventh day, me and my boyfriend have unprotected sex all the time but we always get tested ever three months.. thats not the point he never cums in me he pulls out. its been 4 days since the intercourse and ive been havin reallly bad cramping frequent head aches and alot of lightheadedness, im always tired <------ ive always been tired im a tired person lolz, but i feel weak with no strength or energry to do anything.. i dont know if this has to do with me stopping my period ahead of time or me possibly be pregnant.... wat do u think?
