Progestin is progesterone which supports the pregnancy by making uterine environment more favorable for conception. It also causes delay in the periods or sometimes no periods at all. I would suggest you to get a urine pregnancy test, of it is negative, then do wait for 7-10 days after stopping the progesterone for the proper periods to occur. Glucophage is metformin which is given to improve the glucose metabolism and hence increase the chances of conception in PCs patient. Cerophine is camphene citrate which is an ovulation induction Chat Doctor. Hope you found the answer helpful. Wishing you good health. </s>
