I had my period January 17th- 23rd. I had unprotected sex with my boyfriend on the 22nd and he did not pull out. The 26-28 I found there was light spotting in my underwear! It's now February 9th and I get little cramps in my stomach every day that come and go. I've taken 3 pregnancy tests that have all come back negative.. am I testing too early? Could I be pregnant?! Please help
