After experiencing a previous miscarriage, it is common for doctors to prescribe HCG (Human Chorionic Gonadotropin) and Progesterone injections as a preventive measure. These hormones play crucial roles in maintaining a healthy pregnancy. HCG helps support the development of the placenta, while progesterone supports the growth of the uterine lining, ensuring a suitable environment for the embryo to implant and grow. By administering these injections weekly for three weeks at the sixth week of your current pregnancy, your doctor aims to provide additional hormonal support to reduce the risk of another miscarriage. It is important to follow your doctor's instructions and attend all scheduled appointments to ensure optimal care during this critical period.
