Progesterone!

Jasmine • Trying for our first baby..more difficult than we thought it would be ?
Hi everyone have been trying to conceive for over 4 years and have had 2 miscarriages ?? had some bloods taken recently and doctor thinks low levels of progesterone are to blame...now I live in the UK and medication like this cannot be bought without a prescription and it is not available on the NHS. Very impatient and our referral to the fertility clinic is taking FOREVER!  Wondered if any UK ladies are or have been in the same boat?? 
Thanks xx
