After the embryo transfer, if there is a brown discharge, it may be caused by bleeding during the egg retrieval. If the bleeding is not that heavy and not as severe as bleeding during menstruation, you do not need to worry too much. If the bleeding is as heavy as menstruation, you must go to the hospital for a checkup, as it may be a failed transfer. If the bleeding is not excessive, there is no need for treatment. Try to rest in bed, it is okay to go to the toilet, but do not wash your hair or take a shower for a short time. If you experience this phenomenon after the transplant, it may be due to bleeding from some parts of your body during the egg retrieval. If the bleeding is accompanied by severe stomach pain, it is recommended to go to the hospital for a timely checkup and to undergo fetal preservation treatment. If there is a preterm miscarriage without any sign when the transplant is around 14 days old, it is important to actively perform fertility preservation. This is because many of these preterm miscarriages are due to unstable embryo implantation and require fetal preservation treatment, with commonly used fetal preservation drugs such as progesterone capsules and dextran. At the same time, you should also pay attention not to overwork or overexercise, and try not to eat spicy and stimulating food.
