Question on opks??? Help appreciated

[Lookingforadvice15]

Second month ttc, second month using opks...not temping.
Last month i got + opk on cd14 we dtd that day and cd15.
This month we dtd on cd13...i was trying to pre-empt the fact that i thought i would get a + again on cd14....didnt happen.
Got a blazing + this morning cd16...so we have dtd today already.
So dtd cd13 and cd16 would that be enough dp is away with work for the next few days.
The cramp i have today is unreal! Worse than af....is it possible that i am ovulating today...even though i only just got the positive today??

Yes, it's possible to ovulate on the same day you get a positive opk. The older you get, the closer to your surge ovulation occurs.

It's also possible to catch only the tail end of a surge, depending on often you test.

If you're getting ovulation pain, that's a pretty good indication.

The number one lesson of ttc - if in doubt, shag
