Im 9 days late for my AF. and no sign of it showing up. I am having pregnancy symptoms. but I have to take in about five or six pregnancy test and they have all been negative. here's what's happening: my boobs are sore but not too sore, I'm having headaches, my lower back hurts, and I have thick white discharge with no smell or odor. Sorry tmi. I want to know if I'm pregnant or not. can anybody give me some advice. has anybody ever had a negative pregnancy test and actually ended up pregnant? any advice would help me. Thanks, chelle.
