Anyone had the HSG test ?

Janine
I'm British Im almost 33 been ttc for over a year Drs say everything looks good normal, but frustrating because nothing has happened. I decided to have this HSG test to see if my tubes are clear. Supposed to be painful? But i hope it will tell me something. I'm thin but have a big belly that's worrying me as i eat healthy could it be a reason why im I'm not getting pregnant? Has anyone had the hsg and had luck conceiving? Xxx
