Contractions BH

So I am currently 30 weeks and 6 days  and since I was about 24 weeks IV been getting these  tighting pains in my upper stomach that would last for a few minets and then go away. They come at random times  I am trying to figure out if these are contractions or BH . Having  some back pains  and period type cramps also  help ?
