just popping in...
beau - i have used the progesterone injections (think they're sometimes referred to as PIO - prog. in oil). anyway, i didnt find them painful which was as big relief bc i had read that they were too. they are injected intramuscularly (in the butt for me!) & i had one jab every 2nd/3rd day from memory. the bottle was about $65 & there was about 3-4 doses in a bottle. i tried the injections bc i seemed to be having low prog. levels for a couple of transfers using pessaries/crinone. goodluck with it all. xx
