CD 21 and just got a positive opk on clomid

Lauren

I took clomid 50mg this cycle on cd 3-7 and I read you are supposed to ovulate within 7-10 days which would’ve been about 4 days ago. Today is cd 21 and I finally got a positive opk so I should ovulate soon.

I’m just wondering is this really late to be ovulating? Has anyone else ovulated this late on clomid and got a BFP and had a healthy pregnancy?
