Had a positive opk on the 1st, AF was due on the 17th. 2 weeks late and 2 bfn... no sign of AF yet either and it's driving me mad! Never had a period this late before, I'm always like clock work
The only way you can know for sure if you’ve ovulated is to confirm your OPKs by temping. You have LH surges throughout your cycle. Sometimes your body can gear up to ovulate then for some reason it doesn’t happen so it will try again a different time.
Good luck, if you’ve been having sex regularly there’s still a chance you could be pregnant but it may be too soon to show up.
