Help with Ovulation timing


Opinions please....

LH surge testing

CD#11 looks low

CD#12 test #1 looks high. 14 hours later I re-test and it looks low.

CD #13 both look high.

I initially thought CD 12 was my LH surge resulting in my OD being 12-36 hours later. However CD 13 looks high too. What do you think? According to my cycle calculations today CD#14 is my OD.

When do you think I ovulated? The strips are so close... Ahhh!!!
