I'm on my period and i have pain in my abdomen and i start crying for no reason, is thus normal?

not normal: At 42 yo, i suspect you have not had these symptoms occurring in the past, change your normal menses would mean something is amiss. Mild cramping/pain may be normal for some women, but if new or severe, than get an evaluation with gyn. Crying for "no reason" may be a sign you are getting stressed and depressed as well. Best to see a doctor. Good luck to you.
