FERTILITY SPECIALIST QUESTION

Okay so I went to obgyn they scheduled an hsg for me and an seamen analysis for my husband said he had to go to a labcorp and get it done. Told me we could just drop if off at the labcorp. Not true he had to schedule an appointment for it Nd they only have ONE location in my state for it and he couldn't get in to January. I literally almost cried while he was telling me. We have been trying for two years. My question here is do fertility doctors or facilities do seamen analysis in their centers ?? Or will he have to go to a labcorp still ?? I mean if I have to wait till January then I just have to wait. Just a little disappointed thats all. I know I should be happy that I'm getting this far im just sad that I have to wait longer for answers and maybe I'll get pregnant from now till then. Just a little discourage thats all.
