The embryo transfer procedure is generally not painful and is similar to undergoing a pap smear. Some surrogates might experience cramping during or after the procedure, which can be a positive sign of embryo implantation, but it’s not always present in successful transfers. The process is designed to be as comfortable and stress-free as possible, with medical professionals on hand to ensure your well-being throughout the procedure. Understanding that minor discomfort or cramping could occur helps prepare surrogates emotionally and physically for this step.
