Secondary Infertility I Guess..

So 😣 my cycles are irregular(I wont have my own period without provera, & have been this way even with my other 2 children(10&12 years old) I have tried Clomid at least 5 times up to 150mg and nothing, although I did ovulate. I am now on Femera tried 2.5 and it didn't work. So my cycle started and I am taking 7.5mg Femera. I have my HSG schedule for next week and then follicles checks. I'm just so happy I finally have a fertility specialist who is actually helping me and my insurance cover EVERYTHING. My specialist thinks after the HSG we will get pregnant. I'm prayer we get pregnant, we have no kids together and have been trying for 6 years. IUI is next, but I think we aren't going to need it. Just hope the HSG isn't that bad, I'm so nervous. Praying this is our time!😩🙌
