My doctor doesn't think it's necessary since I had one about 4 years ago and it was normal. I had a c-section with DD so she doesn't feel that blockages are a concern.
She does want to do a SHG though so I have to call when AF shows to schedule that to check for cysts, polyps, fibroids, etc.
Re: Yay for no HSG.
Mine was as well. I cried through the whole thing while a nurse held my hand.
She doesn't want to put me through it again if it's unnecessary, which she feels it is.
