I have had the problem that IF i ovulate my luteal phase was between 1 - 4 days. I have been given clomid (i also have POCS) on days 2-6 and then after ovulation i started progestrone to extend my luteal phase. last month i got i think 14 day luteal phase and this month i am not sure yet as i get the test results tomorrow.
I have tried 2 different types of progestrone and i have a bad allergy to the pesseries but ok on the gel. if your luteal phase is short you are going to need help from a specialist which your doctor should be able to refer you to
