On CD35, I will take two pregnancy test (always come back negative), then start the Provera. I've only ever gotten a positive OPK ONCE since using Provera (and I was using Soy at the time to bring on ovulation) so Provera definitely did not increase my LH surge. Also, for the majority of the time I've used Provera with the OPK's, I only ever have stark white negative OPKs or faint lines, indicating some LH. So Provera has never had any affect in that sense to me. Provera will eventual stop that ovulation from happening and it doesn't cause positive OPK's - so could be this is finally ovulation for you. Cause you are still earlier in your cycle and there still is a good chance you can ovulate on you own, might be a good idea to hold off on the progesterone for a little as there is still a really good.
