How bad are your cramps?

I was reading someone’s post that said periods should not be painful and I was wondering if that was true. So for those of you that do not have endometriosis which I know is quite painful, how painful is your period? Are there people out that that don’t need pain relief?

Personally, I’m taking 8 Advil a day for the first three days and I’m still uncomfortable. I also have to have a heat pad on for the duration of the period or I can’t function.
