Can natural progesterone be used during a pregnancy?�

In his book, "Premenstrual Syndrome & You", Neils H. Lauersen, M.D., from Mount Sinai Medical Center in New York, states that natural progesterone may be helpful to maintain pregnancy.

The cream in not only safe for use during pregnancy but is recommended. From conception to delivery, apply primarliy to abdomen, breast, low back, and upper thighs (where it will tend to prevent the skin from stretching).

For the first six months of pregnancy, use an average of 1/2 to 3/4 teaspoon 2 to 3 times a day. Discontinue at delivery and resume again at a level of twice per day starting one month after delivery. The cream is also useful for post-partum depression, which many women experience after childbirth.�
