First I want to say that I'm happy your doc is doing the Hysterosalpingogram (HSG for short). If they find a block they can either usually open it up or clear it out, that would be good to know. I felt so much better just knowing after I had mine...no blocks for me, so they don't know why it took two years, but I do have some tips for clomid when you do start taking it. Feel free to ask any questions I'm not a doc or anything, but I did do 3 rounds of clomid with all the BBT's and OPK's and AAAHHH! It can seem overwhelming, but if you take it one step at a time it becomes more manageable. Sorry I don't have info on the insurance, I do know that clomid is one of the cheapest ways to start, but I have military insurance so I don't see the bills. I hope this helps and once again let me know if you need any tips for clomid. Good luck and keep us posted!!!! Sorry to ramble on :P
