Hi!
I know we all here use OPK often when we are trying to predict when we need to have intercourse while using Clomid. =) As far as the Metformin, I am not familiar with that, to be sure I would call your doctor and ask if that drug interacts with the OPK results.
Good luck and welcome to the Clomid Club! I hope your stay is short and sweet. =)
God bless!
