The medications your wife is taking, including human chorionic gonadotropin (hCG), hydroxyprogesterone, micronised progesterone, L-arginine, and folic acid, are commonly prescribed together to support early pregnancy and are safe under medical supervision. By the 14th week, the placenta usually takes over hormone production, meaning hormone support like hCG and weekly progesterone injections may often be safely tapered or discontinued. However, this decision depends entirely on her specific medical history (such as a history of recurrent miscarriages). Please consult her obstetrician to re-evaluate her current needs, as they can safely guide you on whether to continue these injections.
