Hey I have had unprotected sex for almost a month now and I am having early pregnancy signs. Cramps, feeling nausea, back ache, head aches, frequent urination, and my nipples are just now getting darker (just to name a few).I have taken two pregnancy tests and they both came out negative. I read online an it said they could be false negatives since I would be about 4-5 weeks pregnant, I want to know if I am .... I had my period October 7, and had sex during then too. Am I pregnant?!?!?!
