I'm on cycle day 69 and AF still hasn't shown. I take HPT's every couple days and they've all been negative. They're the cheap internet strips but they should still detect any hcg right? Being 2 months late is so annoying. For the past 2 weeks I've had terrible high and low back pain. Just the last few days I've had a strong sour taste in my mouth, watery mouth and strong cravings for salt.
