Postmenopausal spotting

Hi 

Just need a little support.

I had a transvaginal scan today and they tried to do a hyroscopy but the entrance to my womb is too narrow, so I have to wait for an op under general anesthetic.

Im the meantime the specialist has referred me for blood tests for all sorts one being ca125 test and other cancer tests. Is this routine or does he suspect more.

Ready scared.
