Oh wow! I am so sorry you've gone through all of that! What a devastating blow!!

I really hope the Provera helps and you can get to the bottom of this on your next cycle. Just a word of caution though, a + OPK doesn't necessarily guarantee that you are definitely ovulating. You can have an LH surge without ovulating. It definitely helps to back it up with temping...because that will confirm ovulation occurred. Please keep us posted on how you are doing! I hope that you don't have an ovulation problem and that this was just a fluke. If it is an issue, then I'm sure the Clomid will help a lot! Sending tons of prayers that you have a great, natural ovulation next cycle and get your BFP!!
