How can i tell if my period is going to start because i been having bad period stomach pain but havent started my period yet. can you have a month where you skip your period but you have menstrual symptoms and premenstrual symptoms?

In biological sciences the only certainty is death and uncertainty. If your family is complete then missed period has no significance. Pregnancy should be checked. Symptoms of premenstrual and menstrual periods are hormonal, bleeding is sloughing of endometrium. It is possible that hypothalamus pituitary ovarian axis is ok, wait for 3 months if not back to normal, see Gyn. Hope it helps.
