Do girls have people who never have a stomachache during menstruation?

Yes

I just, growing up, never had menstrual pain. At most, it's stomach upset. But don't worry too much about your stomachache when you have your period. I can help you change a few tricks.

Apply a hot water bottle to your stomach: hold a hot water bottle in your stomach on the first day of menstruation, and your stomach pain will be relieved. It is very important to keep warm for dysmenorrhea.

Practice yoga: Go to a yoga instructor and learn some actions to regulate menstruation and relieve dysmenorrhea. This can also regulate dysmenorrhea.

Taking vitamins: It is recommended to take comprehensive vitamins and minerals, preferably calcium, in small doses, several times a day.

Mineral supplement: minerals such as calcium, potassium and magnesium also help to relieve dysmenorrhea. Experts have found that women who take calcium have less dysmenorrhea than women who don't take calcium. Magnesium is also important because it can help the body absorb calcium effectively. It is suggested to increase the intake of calcium and magnesium before and during menstrual cycle.
