Hello: You just finished the ring surgery and you didn't feel well at first. It is normal for you to have a stomachache. Because this is also an intrauterine operation, there may be abdominal pain or discomfort after operation, which generally does not last long. So it's normal for you not to feel sick the next day. However, the ring is prone to shift, ectopic and fall off one month after the upper ring operation, and the position of the ring needs to be re-examined one month later.
