this is something worth giving it a go. josie and david are now the furthest they have ever been into a pregnancy. and at 15 weeks they are cautiously optimistic. now we are trying to switch the feeling is to be excited. yeah, we get to see it and it's going to be ok. afterfour orfive, how the hell are you hopeful it was ever going to work? and thankfully, progesterone does feel like that miracle thing for us. some doctors do already prescribe progesterone, but it can be a postcode lottery. this changing guidance means it will be much more widely available to women. this is a very significant moment. we have an intervention that works, that can stop a miscarriage. this would give hope to thousands of couples. but it's really important to appreciate that only some miscarriages can be prevented by progesterone. there are other causes for miscarriages and not everybody would benefit from progesterone.
