Provera/clomid through gyno??

Layne
I am in desperate need of some feedback. My cycles have been irregular for the past year. They were always normal before that! My gyno did blood work on me. I went on cycle day 10 and cycle day 24. My progesterone was low (2.1) but I had a positive OPK just 2 days before on day 22 so I really think I should be going back for a blood draw tomorrow to get the accurate number. She wants to put me on Provera and Clomid. Part of me really wants to just do it and see what happens but then the other part of me feels like I should go to a fertility specialist for extensive testing first. I am prone to migraines so I'm sure these medications are going to wreak havoc. Help!!
