Is it true that if a girl doesn't feel any pain before and during her period she would feel the pain after becoming a women?

You will be fine: Don't worry every female do not have pains during periods , if you don't have it now , most likely you are not going to have pains as you grow older.

No: Some women experience pain with their cycles and some women do not. The symptoms experienced by a woman may also change during her reproductive years. If you are experiencing particularly painful cycles, or have other concerns, see your doctor. There is treatment available that can help with your symptoms, for example, some form of birth control.
