Hoping you lovely ladies can help me....

I only just started charting- so please forgive some of my missing temps.

Check out my chart, I thought I O'd on day 12 or 13.
I got a +OPK on those days.

Is it a possibility that I actually O'd later? Say like day 16?

Maybe I'm grasping at straws here- but I had a temp dive today and I dont want that to mean AF- I want a BFP!!!!!!!!
I did take my temp 1.5 hours later this morning.......
