Hello, looking for some help with my bbt chart so far, yesterday I had peak opk with solid smiley and ov pains, and a big temp shift, then this morning I temped at my normal time and got a ridiculously higher reading (37.8 degrees), is that normal 2dpo? I then re took the temp a minute later and it was 36.5 degrees which was really weird, not sure which temp would be right?
