My period hasn't come on. Took a test and its negative.. so i hv to take provera to mk myself hv a cycle. Is it safe to take Geritol while taking the provera? or should I wait til my 10 days to tk the provera is over and start it? I also take prenatal gummies and metformin for my pcos. Is is safe to take metformin, provera, Geritol and the gummies altogether? I dnt want to overdue it.
