Did I ovulate?

Marcquita

So this is my first time doing an OPK. I’m not sure if I actually ovulated. I had my progesterone levels checked on day 18 and it was a 13.5. Which would indicate I did ovulate. It is now day 21 and I’m having a white milky discharge. I feel confused lol I keep looking online to see what all this means but it’s messing with my head. Mind you we have been TTC for 8 years now and I’m currently taking Clomid since I don’t ovulate on my own. Thoughts?
