HI,
I am 24 years old and in good health and I am not on birth control. My periods are usually normal 7 days 28 day cycle. On December 2nd I started my cycle, towards the end of my cycle on December 5th I had unprotected intercourse with my partner. The next day there was no blood as if my cycle had ended, then the day after Dec 7th I only bleed a little for that one day, not enough to fill a tampon, the blood did look different, not really dark brown but not bright pink. December 8th I was nauseous for about 15 mins in the morning and had tingling nipples. Today December 9th, I am experiencing some mild cramping. I'm wondering if this could be a pregnancy, or the side effects of ovulation?
