Miscarriage?: A history of previous miscarriages in early pregnancy if based on inadeaquate progesterone production by the ovary up to 8-10 weeks of pregnancy may benefit from progesterone supplementation, but after 12w of pregnancy, it can be stopped, as the placenta will produce sufficient amounts. Progynova is estradiol, and it is not necessary for miscarriage protection.
