help with opk's please

[tootyfruity]

So normally i have a good idea when i ovulate as i start doing opk's around cd11-12 and i normally see them get stronger and will get a strong positive on cd13,
today is cd13 and this morning i got an almost positive on opk so i thought tonight should be stronger but i had hardly any second line at all.

Could i of missed my positive opk (which could of been yesterday?) or is it likely to go positive in the next few days?
i feel like im out already this month, im also worried as last month and this month i have had hardly any cm. we have been using preseed. now im worried that my fertility is deteriorating

Keep testing, I'd say... it's normal to have an atypical cycle once in awhile! Keep BD'ing... you might be ovulating later this cycle for whatever reason. Try not to stress

Its possible your surge could have been strongest yesterday, or maybe you drank a lot of water today which threw off your test tonight?

Thank you ladies, uniquebeauty that's really interesting!
Purplecupcake I did drink lots of water so might not of helped.

This morning I got a faint line again then I just tested this afternoon and got an almost positive again so will keep testing and bd'ing. I wish I would of tested Thursday but trying not to obsess about it lol. Not really working! X
