Clomid and late ovulation

I was taking provera to regulate my period for a few months and just started clomid on day 2 of it- my question is when I wasn't taking the provera I would get my period every 40-45 days almost skip a month in between and so I'm wondering if that means my body will ovulate later than the normal 16 days from your period? Or does clomid make u ovulate more regular if it works at all- I am only on 50 mg-
