progesterone tablets?

Georgia
Hi ladies was wondering if anybody had been put on progesterone tablets and knows how to go about it or what the requirements are? I've had 2 miscarriages since having my son 7 and a half months ago and am now pregnant again. All planned as it's been advised we try again sooner rather than later as I have problems during pregnancy and the older I get the more I'll struggle and I've heard of people being put on progesterone but was wondering if the docs would actually do it for me? TIA X
