Ok, so I started the progesterone suppositories today...twice a day I am supposed to insert...however, I need to know the rest of the neccessary information. My period is due on Tuesday October 12, so will it come? even if I am not pregnant?? And if I do a negative test, then do I stop the suppositories until I ovulate again?? Please advise, as my OB didn't give me much information. Thanks so much!!
