For you ttc ladies: how much did your bbt drop the day or 2 before af? Have only been check8ng it for the past week or 2, and it's hovered around 97.7 pretty steady I guess. This morning it was 97.4, but I took it after waking up a second time. The first time I had got up and went to the potty bout and hour and a half before. Is it likely I'm fixing to start, or am I still in the running? I'm just frustrated.. Af expected date is today.
