No, you cannot be an egg donor while you are pregnant or nursing. In a retrieval cycle you have to take follicle stimulating hormones which might be harmful to your baby. You will also receive conscious sedation for the egg retrieval. If you are pregnant, your body is not currently stimulating eggs. You will need to have had at least two spontaneous periods after stopping breastfeeding before you can donate. You may apply while you are breastfeeding but we will not be able to match you until your cycles return.
