Hysterosalpingogram (HSG)

Tara
Has anyone gotten this done? If I'm not pregnant this month my doctor is sending me to get this done but she told me to wait that month and not try to get pregnant following the exam but I am reading so many people saying you're super fertile right after and that the x-ray fluid releases from your body quickly so it is safe. I have even heard many women say they got pregnant that same cycle. I just wanted to know anyone's experience with HSG
