Hello dear I understand your concern Hormonal changes, Infections Subchorionic hemorrhage Miscarriage (either threatened or imminent): usually accompanied by other symptoms, such as cramping or abdominal pain. Ectopic pregnancy Molar pregnancy, characterized by an abnormal growth on the placenta, and, usually, an abnormal fetus. I would suggest to consult gynecologist as early as possible and undergo examination and USG scan to know status of pregnancy. Take complete bed rest maintain proper pelvic hygiene Drug containing progesterone can be useful to stop bleeding Other specific treatment depend on cause Best regards Dr. Sagar
