Hello, and I hope I can help you today. In general, it is recommended that you wait until you resume one menstrual cycle before trying to conceive again because otherwise it can confuse the dating of the pregnancy. However, your doctor prescribed you prenatal vitamins possibly to treat any anemia from blood loss from the pregnancy, to regain your strength and make sure your menstrual cycle returns to normal. So you really do not need to wait longer than one menstrual cycle to try to get pregnant again but waiting for a few months may be beneficial to your recovery. I hope I was able to adequately answer your question today and that my advice was helpful. Best wishes, Dr. Brown
