very late positive opk after bcp?

[gumballgirl]

HI I'm new to the boards with a question!
I have just gone off bcp this cycle hoping to start charting on my next cycle, however my af is taking forever to show up! I know this can be normal after coming off bcp. I had baught some opk's ready to use next cycle but decided to try one out about a week ago to see how it worked, and got 2 very dark lines which i think means i was about to ovulate? this would have been just over the fourth week of this cycle. We dtd that day, and i just wanted to know if its possible to ovulate that late and get pregnant? I have extremely sore nipples right now, as well as twingy cramps but would have to wait another week to test!

It is possible to ovulate that late. OPK's can also be positive if you were pregnant. Is that possible?
Wishing you luck...
