Typically, the placenta fully takes over progesterone production around 10 to 12 weeks. For those with a history of miscarriage, doctors often recommend continuing progesterone support until approximately 12 to 16 weeks of pregnancy. Since you are currently at 14 weeks, you are likely nearing the time to safely discontinue it. However, because every pregnancy is unique, please consult your OB/GYN before making any changes. They will evaluate your specific progress and advise you on the exact timeline to safely stop the medication. Wishing you a healthy and happy pregnancy!
