I'm not trying to have a baby I have 2 kids and that's plenty. I always know when AF is coming and put a pad on. Well I've been waiting 3 days. I didn't think anything of it until yesterday I'm due for my period on the 18th. I took 2 tests yesterday afternoon. Both negative. A sigh of relief but today still nothing.. I felt slight cramping yesterday before bed but nope nothing yet not even a drop. We had sex on jan. 1st and 6th (we live separate) could the neg. Be false because its early :/ since I'm thinking I am my symptoms are ich breasts, constipation and 2 days before my missed period I craved ice cream thought it was because AF was on her way then the day after I was barely hungry at all..
