35 weeks and feelings need some help.

Ok so i am 35 weeks and a few days and today what i think are contractions happened really bad. The feeling is tightening in my stomach and a pressure in my vagina, it goes away after about 2 minutes. But my stomach stays tight for about another 30 seconds. But i made dinner and after eating it has gone away thank goodness. But should i start counting or maybe its Sebastian way of saying he is hungry. Anything will help thank you lady's.
