Is an HSG worth it?

So I'm 34 yrs old. Had one tube untied a year ago and have had zero positive pregnancy tests.

I'm tracking bbt, LH, CM, periods, you name it - so I know I'm ovulating.

I completed two rounds of clomid a few months ago and nothing happened.

The obgyn suggested running dye through my tube to make sure it's open. It's going to cost me $1224 out of pocket because I have terrible insurance. My insurance will cover it but after I meet my 3500 personal deductible and/or 6k family. I haven't met either deductible yet.
