BBT rise AF due

nikki

Okay so i was soooo certain af would be coming on time (due today) since yesterday my bbt dropped as it usually does before af comes. I had cramps on & off yesterday & had to put a liner on cos i really thought it would come any second. However… this morning my bbt is up high again! Has this happened to anyone & ended up with a bfp?

I’ll test later today but just curious if this has happened to anyone else too :)
