Most of the pain in the abdomen is normal after placing the Mannix IUD, which is mainly due to the contraction of the uterus after the IUD is placed and the stimulation effect of the IUD on the uterine wall. In most cases, the pain will not last long and can be relieved in 1-2 days, and the feeling of a slight soreness in the stomach area, similar to menstruation, can be relieved soon after the procedure with proper rest. In the week following the IUD, it is advisable not to engage in strenuous exercise. At the same time, there will be a small amount of vaginal bleeding after the IUD, so at this stage, pay attention to hygiene and prevent infection.
