First month tracking BBT. Monday-Friday I take temp at 4 am. Saturday and Sunday around 7:30am. Af is to arrive Monday according to Glow or Thursday according to FF. I couldn’t sleep and took my temp at 3am this morning and got a huge dip! I also took a FRER with FMU and within timeframe for what I thought was a faint line but not sure. Is AF coming? Did anyone get a BFP with a chart like this? I got my PEAK OPK the 2-16.
