I have used the progesterone suppositories, the prometrium which I am taking now and the
cream. They do all bring up the
progesterone but if you are ahving contractions the
cream is best to sue along with the pill as it goes directly to wher you need it. The pill goes through your system first and through your liver then to your uterus. So you have to ahve blood work to make sure you are on the right ammount. This is my 7th pregnancy and I have had 4 pre term babies.
