I'm ttc no 3 and this is my 2nd cycle off pill. I had positive opks Monday to Friday last week which was odd in itself, on sat the opk was negative but I never felt myself ovulate and I normally do 
Did a first response test yesterday which was negative, but today I was really tender when sitting down/ getting up and generally sore. I did assume was af coming but as time went on realized that's how I feel when ovulating.
Just did opk and it's positive
it's cd 25. What the bloody hell is going on?
