It is normal to have slight abdominal pain after egg retrieval, after all, it is a minimally invasive operation and will gradually ease after 2-3 days, so don’t worry too much. After egg retrieval, you should take rest and avoid strenuous exercise and heavy physical labor, eat a light diet, prohibit smoking and alcohol, take a shower and not a bath to avoid infection, and prohibit sexual intercourse for about 2 weeks after egg retrieval. If the abdominal pain is severe, or if the abdominal pain is not relieved, it is recommended to consult a specialist as soon as possible to have the cause checked and treated symptomatically. Some women may develop pelvic fluid after egg retrieval, resulting in abdominal pain and swelling. If the amount of fluid is small, no special treatment can be given and attention should be paid to regular review.
