Hello aliana! I moved your post to Trying to Conceive because I think you will get better responses here. I'm not sure I understand your question. Progesterone supplementation is normally used after ovulation and during the first trimester if you do become pregnant. I have never used the cream, but I took progesterone each month after ovulation when I was trying to get pregnant.
