I had my period last month oct 20th-25th, me and my fiancé have been trying to conceive and the last time we had sex was when I was ovulating. I am 5 days late for my period and I have taken 2 home pregnancy tests and they both came out negative. I have been having pregnancy symptoms such as - nausea, sore breasts, emotional, mood swings, constipated, I stay hungry but everything I eat just doesn't cut it for me and makes me sick to my stomach, all I can eat that doesn't make me nauseas is Popsicles and smartie candies, I can smell food from a mile away, an I have a really nasty taste in my mouth and keep back aches and headaches. A couple months ago I went to the dr and they put me on prenatal vitamins because I told them I was trying to conceive. Someone help! :) thanks
