That will vary depending on the individual. In an average retrieval cycle you will be taking a series of subcutaneous (small needles injected under the surface of the skin) shots over an 8 to 14 day period to cause you to produce a number of mature eggs instead of the single egg that normally develops each month. Throughout the process, the doctor will use blood tests and ultrasounds to monitor your health and the development of your follicles. You should not feel any pain during the egg retrieval procedure itself because you will be under light anesthesia. Some donors have reported soreness and discomfort the following day.
