Hi, I'm really upset about my sonohystogram that I had done today. I am currently going through a mock cycle for IVF using donor eggs. I have had a sonohystogram before with no problems except they found polyps. so i had a polypectomy to remove them in july, well i went in for another sonohystogram today and they weren't able to get the catheter passed my cervix...I am just freaking out getting so upset that there may be something wrong now that might decrease my chance for success when I do the transfer. Has anyone had this experience or heard about it....is it something to be concerned about? what would cause this to happen? could it be scar tissue from the hysterscopy/polypectomy? if anyone can give my any info, I'd really appreciate it..thanks
