Yes. Pelvic rest has been shown to help subchorionic hemorrhage in some patients. The practice of pelvic rest is thought to help minimize blood loss and improve the condition of the uterus. However, certain factors must be considered when doing pelvic rest, including the severity of your subchorionic hemorrhage and how long you plan on doing pelvic rest for. If you have very heavy bleeding or an infection that could cause further damage to your uterus, you may want to consider other options first.
