After egg retrieval, your body faces hormonal changes; as a result, your first or second period after egg retrieval may be missed or delayed, which is quite normal. In most cases, people have their first period 10 to 14 days after egg retrieval, but having the second period depends on when they will ovulate.
Since ovaries are enlarged and painful after egg collection, it is better not to have sex for two weeks after the operation. After 15 days, you can ask your doctor if you can have intercourse.
A needle and a suctioning device are vaginally inserted into the uterus during the egg retrieval procedure. So, it is common for patients to experience mild spotting or bleeding after egg retrieval. However, if spotting or cramping were severe and lasted more than a few days, contact your doctor.
