Not necissarily. Menstrual cramps are common, with around 80% of women experiencing menstrual cramps at some point in their lives, however menstrual cramps are not a normal part of healthy menstruation so not everyone gets them (and if you do there are ways to prevent them). Menstrual cramps can be more common in your pre-teens and teens due to hormonal imbalance, so you may get menstrual cramps during your first period...but you may not.
Backache is part of menstrual cramping. The hormones responsible for the uterine contractions can also effect muscles elsewhere in your body, pain from menstrual cramps can also radiate. If you get menstrual cramps then know that they are preventable, don't just suffer them.
Menstrual cramps are common but they are not a normal part of healthy menstruation - it's when you have menstrual cramps that there is something wrong.
