Planning for HSG?

Jennifer • Hey everybody :) My name is Jennifer. I have a 5 year old from a previous marriage. My husband and I have been TTC for a little over a year, and have had 2 m/c. Due April 20 with our rainbow baby boy!
We're planning on scheduling an HSG. Has anyone's doctors told them to stop TTC until the testing is over? I'll be calling my doctor tomorrow to ask, but was curious what you ladies were told. I'm having an HSG due to recurrent miscarriages. Thanks in advance!
