I had this pain that started early this afternoon and last ~4hrs. It is a stabbing/burning type pain in my right side, but high up. It would only last a couple seconds and then go away, but this was happening every 2 mins over 4 hrs. I didn't notice any tightening over my abd. that would make me think they were contractions, but the time pattern had me wondering. Anyway, I drank a couple bottles of water and tried to take it easy and it finally went away. I didn't call the OB, but it I notice it again I will definately contact my OB.
