I have been having the same bbts for the last six days. This has never happened. My bbts have always been all over the place. I have always been irregular. But since i have been taking Fertilaid (to help balance hormones)i have been getting a normal AF. My cycles last around 35days give or take a few days. And af for about 10 days. I can never tell when I OV. I've been ttc useing bbt and cbfm for 5 months now. Ive had 14 days of HF with cbfm still no peak. But i think that might be my fault cause i was testing in the middle of the day for the first 5 days instead of fmu. Then i continued with fmu. I have soar breast, acid reflux, pelvic pain, major headaches every morning for a week. I guess i just want to know if this is familiar to anyone? Any advice would help.
