Yes the HSG is the Xray one to check your tubes and the lap is under general. I was thinking if you have suffered from VB for ages it might be worth a look into seeing as you have been ttc for a long time. But it sounds like its a fairly recent thing. Was only thinking that as it can cause tubal problems but thats only really long term side effects. It would take years for it to cause problems.

Maybe you could try the vaginal antibiotics. I had to use it for 7days straight daily. It was gross (as it melted and leaked back out and would run up your butt crack). It did help but didn't cure me for long. Better then the oral ones. I've had them before for the PID and they made me so sick.

Could you just pin point your O day and DTD unprotected just the once this cycle so your still in with a chance? DH and I did this on the cycle after my lap and dye when I was super sore as we didn't want to miss any chances.
