Progesterone creams?

Has anyone used it trying to conceive. I have had a progesterone test on cd 21 and it was only a 13 which is in normal range but on the lower side. I have miscarried twice in the last 2 years and I feel like low progesterone was the cause for some reason I just feel that. I am going to use the cream while trying to conceive this next cycle and wanted to know if anyone has used it and if it has helped anyone conceive?
