New to this. Taking Femara for 3 cycles. I started what I thought was my period, it only lasted 2 days, very light, normally 5+ days and horrible; not so much this time. I took 2 store bought tests, both pos. took blood test, it said neg. took more store bought test, they said neg. I can't take this confusion. Has anyone else run into this?? I have to wait another week to take another test.UGH
