Anyone out there using natural progesterone cream?

After stopping birth control pills 10 months ago I am finally getting some results with natural progesterone cream (progonal). This is the first month of trying stopping the cream to induce a period. I am hoping I will ovulate in 2 weeks and all will be normal! Has anyone had success with this method of regulation? I was told with my natural levels of progrsterone I would not be able to keep a pregnancy.
