Hey Rilla,
I take Clomid to ovulate as I don't on my own.
When taking Clomid I ovulate anywhere from day 18 to 24 (I just O'd a couple of days ago on day 20).
My LP is 13-15 days long.
My gynae had hoped I'd get a 28 day cycle out of Clomid but it didn't happen for me... but it did make me ovulate so I can't really complain lol
I'd assume you'd O earlier than day 24 on Clomid, but it may not be the ideal day 14, could be inbetween days 14-24. But I have my fingers crossed you get it earlier than normal... long cycles are a drag lol.
Good luck
