IUI was a bust :(

This round of IUI was a bfn. Called to report cd1 on Friday only to be told that the dr wants to do a saline sonogram. I just had that done right before this round. All of a sudden the nurse says that the lining of my uterus got thick from the femera 7.5 mg dose I was on. This was never mentioned at any time when I went in to have US done nor when we had iui done on the 7th. I am beyond pissed that there was no communication with me on the findings and let it be known. Well I have to go in Tuesday morning at 7 a.m. for an US and the nurse stated that the dr might want to do a biopsy. When the sonogram was done she stated everything looked fine and commented that my ovaries were photogenic. I am not sure what to make of this nor how to feel. I did not have these issues when trying to conceive my son. Rant over
