Hi, dear I have gone through your question. I can understand your concern. Duphaston contain progesterone. It indicated if you are trying to conceive. It has few side effects when you used it in pregnancy but for assisted technique and for conceiving it can be used. Even if you don t have any miscarriage or abortion then also you can use it. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
