Periods are supposed to be painless

Santana
So here's a random piece of infomation for u all.
My shiatsu teacher informed me that a woman's period is supposed to be painless. Even though cramps are an extremely common side effect you shouldn't be constantly cramping up, you should just be able to look down and seeing that you're bleeding and be able to go on about your day. My teacher said that if u you're constantly cramping and having other side effects, that there are imbalances on a psychical level and slightly spiritual aspect.
