Sex after miscarriage depends on the individual. Generally, couples can resume sex when they feel ready, but this time frame will vary from couple to couple. There are physical and emotional factors to consider. On the physical side, many doctors suggest waiting to have sex until the bleeding from the miscarriage has stopped and the woman has had at least one normal menstrual period. Others recommend that couples wait six weeks or more, especially if the pregnancy was longer or if there were complications during miscarriage.
