I need advice, a week ago I went to the bathroom and urinated and noticed a faint pink blotch on the toilet paper around the time for implantation..it was nothing like a period whatsoever after that no more bleeding, well I also noticed I have been wanting salty and sour foods really bad and I feel nausea,headaches,fatigue,dizziness,constipation and vomited a couple mornings ago. I had slight cramping around my belly button at one point and pain during sex well I also I am currently three days late for my period. I took a test at 2p.m and it read negative I need to know what you guys think
