Abortion surgery will not have much impact on future fertility, mainly rest after operation. I suggest you rest for 3-7 days before going to school. Eat more chicken, fish and less seafood, such as sesame oil chicken, ginger crucian carp and other dishes are very good, eat more red dates, angelica, medlar, black beans and other blood-enriching and qi-invigorating things.
I wish you a speedy recovery.
