My Fiance and I have been TTC since 2013. I finally saw a Reproductive Endocrinologist this month after 4 failed rounds of clomid with my OB. I was diagnosed with Insulin Resistance and prescribed Metformin, and also Prometrium 200mg twice a day for 7 days to start my period. I'm supposed to have an HSG test done between CD 3-5. Everything I have read online says that you are not supposed to have any bleeding while taking this pill and my RE and Nurse both said my period wouldn't start until after day 7. I called on day 3 of prometrium because I had been spotting pretty heavily since about 5 hours after I started taking prometrium and has been getting significantly heavier since day 6. I'm calling tomorrow to talk to my nurse and hopefully schedule my HSG test but I am unsure when to say the start of my period. should I say it was the 6th day of taking prometrium when the spotting started getting heavier or say it was today which is the first day of being off prometrium?
Should I be worried about the HSG test, the doctor warned me it would be uncomfortable but other then that I'm going in pretty blind. what happens if my TOM stops before the test? would they still be able to do it? I usually have pretty short and light periods so this pill is really taking a toll on me.
