There will be slight abdominal pain when you start using it. This is because the uterus is more sensitive and the intestinal adhesion may occur. So, when you use it, you can stand in a slightly curved knee position with low-speed vibration mode. Use it in the morning and night, the pain will disappear in about 7-10 days.
