When should i ovulate after taking clomid?

You will ovulate 5-10 days after the last pill of clomid so I would start testing a few days before that. You will ovulate within 12-48 hours after you get a positive opk. If you have pcos you may get a lot of false positive though. You also don't want to test any sooner than day 10 because clomid can give you false positives as well. Good luck!
