Getting your tubes cleared (cant remember the name of the procedure, but they put dye into your uterus and wait for it to go through your fallopian tubes - it gives them a good clean out or shows if there is any blockage causing infertility).
Many people concieve within a month or two of having that done, I did
I got a referal from my GP for private treatment. It cost about $300.
An HSG, sorry, I can't spell the whole thing..hystersalpingogram or something...

I conceived DS on the cycle I had my HSG.

Good luck.
