You're ovulating
Thought it was bizarre for a doctor to say that!
There are a few people who will get seemingly regular cycles with AF and pos OPK and are supposedly not ovulating. (I say supposedly because I have seen way more people told by doctors that they didn't ovulate because the doc did the ultrasound or bloodwork on the wrong day - and I mean WAYYYYY more like by a factor of 100x, only to end up getting a BFP that month so yeah, they did ovulate regardless of what the doc said)
The data indicates that 95% of everyone who is getting AF + regular cycles (or even CLOSE to regular, even every 2-3 months) is ovulating.
