Lmp 3/10 - 3/14 Opk testing 3/20. Still nothing is it possible I ovulated the time I didn't test with opks? According to glow i was 19 days late last month wasn't testing with opks. Since i was late do i still have a chance to ovulate later if I didn't ovulate those days? It shows I'm exiting my fertile window I know it's an estimate but do i still have a chance to ovulate?
