Progesterone cream anybody?

Hi, I have been using Emerita Progest natural progesterone cream from O to AF for the last 4 months, because I suspect I have a hormone imbalance, or low progesterone. I started using it because I suffer from insomnia in the second part of my cycle, I just can't sleep after ovulation and for the next two weeks until AF arrives. As soon as AF arrives insomnia is gone. However by using this cream my sleep has improved a lot. My husband and I are ttc and I wonder if anybody has used progesterone cream for ttc or getting pregnant? If so, any positive results?? I would love to hear your story. Thxs.
