Vaginal progesterone

Jasmine • Trying for our first baby..more difficult than we thought it would be ?
Hi everyone 
Just wondered I anyone is using vaginal progesterone pessaries for TTC after recurrent miscarriages? My GP won't prescribe me any (no budget apparently) however I do have a friend who lives Spain where you can buy them over the counter who is willing to send me some. Not the ideal scenario I know ...don't judge! I'm desperate ?Just wondered if anyone has used them?? If so how often...throughout the whole of your cycle? It appears the usual dose is 100mg twice daily? 
Thanks
