Prometrium and +OPk

Raven

So this is the second round of Prometrium starting on cd17... I don’t get a positive OPK until the afternoon after Taking my first dose of the Prometrium then it’s practically blaring positive. Progesterone when taken before +OPK will stop ovulation.

Is the Prometrium causing a false positive on my LH surge test? This is the second time that this is happened and I’m starting to become extremely frustrated. Help!?!?
