The swelling and pain in the stomach on the 2nd day after abortion is often caused by the contraction of the uterus after abortion. The residual meconium tissue after abortion needs to be discharged slowly through uterine contractions, so contraction pains will occur. If the pain is mild and tolerable, and gradually decreases every day, you can continue to observe it, and it will be relieved by hot compresses and massage or rest, and will disappear on its own for about 1 week, often accompanied by vaginal bleeding, which lasts for no more than 2 weeks. If the pain is severe and unbearable, it is necessary to consult a hospital promptly to rule out the possibility of uterine perforation after abortion. The ultrasound should be repeated 2-4 weeks after the abortion to find out if there are any residues in the uterine cavity and the recovery of the uterus. After the abortion, you should pay attention to rest, avoid sexual life for 1 month, pay attention to keep warm, and pay attention to the diet with the right amount of high-protein food.
