I had a hysterosalpinogram ~ a procedure where the R.E. shoots dye through your uterus and fallopian tubes in order to get a clear picture or x-ray of your female reproductive system, to find out if you have abnormalities or blockages.
Often, if you do have a blockage, the dye they use to do the procedure being pushed through your tubes will open them up so you can conceive.
Unfortunatley, this usually only works for a couple of months, depending on your reproductive health, if you have endo, as I do, often the scar tissue will return, and cause more problems.
This is a costly procedure, my insurance billed out around $1,000.00 for it, (not including the doctor's time) but it usually is covered if you have infertility coverage.
Hope that answered all of your questions, sorry I didn't see your post sooner...
