I thought that is was possible to have more than one LH surge in a cycle, since the your body can gear up for ovulation several times, which could give you several false LH surges before producing the true surge that releases the egg. That's why I used to have the BD way before the stick said yes and also way after. Basically, we did the BD until I saw a temperature spike. (which I never did since I didn't ov until getting on hormones.)
Hope this helps and I do hope it does mean a BFP for you!
I'm going thru the same thing!!! I'm on day 7 of positive opks, & my temp went up 3 days ago. What is going on??? Help would be great--- this is really confusing!
