Positive OPK, no BBT rise?

Sara, TTC #1💜

Hi all,

I don't know what's up with my cycle this month. I usually ovulate CD14 after a positive OPK, but this month it's CD18 and two days after the positive OPK and nothing. I had awful cramps yesterday and was really expecting a temp rise today but it didn't happen...

I can't see how I could ovulate 48 hours after a positive OPK (my positive was at 3pm)?!

Any thoughts would be appreciated
