I've had a HSG before.

After the junior Dr who was about 12 told me it was "just like a pap smear" I almost kicked the little sh*t off his chair when he was doing the procedure. For me it was very uncomfortable to the point of painful and I was given 50mg of pethidine (which ended up being too much for my small frame - the chief Dr saying "oops, should have given her 25mg). They discovered that one of my tubes was blocked and unblocked it right there and then by pushing a small wire and some more dye through there.

In the month after my HSG though I got my BFP, first in 6 years. I was told that following that procedure my chances increased by 30%. I was like "yeah, yeah" and sure enough it happened. Unfortunately I miscarried though.

But I'd do it all again just to get that BFP.

You'll hear so many different stories about HSG's. I start to think I'm a bit of a wimp as some women have no problems at all with them. I was off colour for a good 24 hours after the procedure.

Don't be scared. It's totally worth it all to find out what is going on and then you can formulate a plan.
It's all good.
