Clomid ladies?

Do I have to do a Hysteroscopy before my OB/GYN will prescribe Clomid? My DH and I have been seeing a fertility specialist but before he will go with our treatment options he wants me to have a Hysteroscopy done to just make sure everything is fine. But in our second appointment when he was looking at my blood test and vaginal ultra. he made the comment he believed I was ovulating regular because how my period cycles were. Etc. so I’m trying to see if we could possibly save 2,100.
