Progesterone and longer cycles?

Claire

My Dr gave me provera recently to help jump-start my cycles (they tend to be 30-34 days), and this is the first month I'm taking it.

I've been on it for a week, and I think I am just starting to get a period today, which is 2 days later than expected. Even with irregular cycles, AF still always showed up exactly two weeks after my positive OPK.

Anyone have experience with this?! I'm going crazy feeling like the medicines my Dr is giving me are doing the opposite of what they should.
