Question please for those who bbt chart. I woke at 3.30am today, i am 12dpo. My bbt took a drop below my line, but i never test that early. Do I discount it and stay hopeful or do I prepare myself for AF? It dropped from 36.7 at 6am yesterday to 36.36 at 3.30 am today. Right now as I type this it is 36.66 but it has been above 37 during the day all week, as high as 37.48. My AF is due tomorrow at 13dpo and I am testing bfn still. I had a light bfp at 9dpo, but i think it could have been an evap, it was very light (frer). What do you think? I feel so sick and crampy that if this isn't a baby it will be the worst pms I've ever had.
