I used to have irregular menstruation when I got really, really fat and whenever I'm stressed out. It happened for 2 years, I think. There were times when I skipped having my period for 2 months. But now that I started to lose weight, and started drinking vitamins/supplements, no delays on period anymore. Yey! For menstrual cramps, I think hot compress might work And don't take a bath with cold water. Warm water [i]dapat[/i]. I dunno, that's what my mom told me. And that's what my highschool teacher told us too.
