HSG, blood work and pelvic MRI

So I don't know where to begin. Well apparently I have two cysts and a growth in my uterus. Mind you my IUI was 5 weeks ago but there definitely wasn't anything moving. Ok so now I have to have a HSG after my next cycle, blood work day 3 of my period. I'm going to try and schedule my mri this Friday. I don't how I feel. I guess I'm glad I'm finding out everything so that I can have a baby, but I'm worried now. The doctor says not to worry about the growth, I work in the OR, so saying don't worry is a oxymoron to me. He said if it's still there when I come back then we will remove it. Okay he wants to rule out PCOS, and any other stuff. Aye just don't know.
