We have had unprotected sex (for the past two weeks), and he came inside me 4 times, twice before my ovulation week, once on my ovulation day and once the day after. Im dying to know if im pregnant or not but wont be testing until Friday.. ive been having a little cramping the last past days both on my lower abdomen and lower back, ive been having headaches on and off since Thursday but today its more like a migraine, and i just feel really sick.. any ideas, or advice?
