Well, first of all, thank you!
Second of all, both of my doctors said that there is no magic regarding positions or regarding propping up on a pillow or elevating your legs over your head afterwards or any of that. Either the sperm is going to get there and do the work or it's not.

So, do with that what you will. It's hard to imagine that we can't manipulate it somehow, but both my reg ob and the specialist said there is no magic in any of that.
And as for the cost, I can't remember exactly, but the progesterone trochets were $65 a month, and I was on those for four months or so.
The fertility stuff cost us around $5000, maybe more. Emily was over a year old before we had completely paid off the doctor.
Then you have to add in the cost of syringes and the sharps container and other stuff. Remember too that this was six years ago, and so the costs would probably be more now. I would have paid any amount, though. It was worth it to me, and now that I have Emily, I know how true that is.
I would recommend seeing your doctor and going through the process (including testing and treatment) however he or she recommends. You may not need much treatment. Clomid alone may work for you. You may ovulate fine and in that case Gonal-F won't be needed. Your SO/DH could have a low count or lazy swimmers. You first have to find out what the problem is or if there is a problem and then base your treatment on that. Does that make sense?
