Are girls supposed to smell bad when they're on their periods?

I mean not like immediately after showering but is it normal to have menstrual odor or does that mean somethings wrong?

Because I've had menstrual odor ever since I first started my period at 12. So I always thought it was normal, I keep reading on the internet that there's not supposed to be an odor.
