Lace

Ok so my last AF was dec5. I have taken a BUNCH of HPT and only a few have has even a vvvvvvvvvfl .. no super positive. . My Boobs are sore I've been nauseous my emotions are all over the place but have been especially bitchy today dr won't do blood till after 2nd missed Af .. my Af has been regular since I removed my IUD in September 15. Any suggestions on what could be up .. also what I should as my dr next month IE tests and stuff

Thank u in advance

Ps the test is the darkest I've gotten at that was over 3 weeks ago only a couple vvvvvvvvvfl and negatives since
