How far a long are you? And where at by your stomach? If its low, it could be round ligaments stretching or your uterus growing. :)
It sounds like round ligament pains :)
Well I haven't gotten a ultrasound yet going tuesday. But umm according to the clinic I went to I'm 11 weeks(: and it's LIke up by ribs or right under. It's not a bad pain or Nun but when I take a deep breathe I feel it.
Hmm.... maybe you have an air bubble trapped? lol Sometimes I get real bad chest pains and it ends up being a bubble... gotta love pregnancy and the trapped air all over the place. :-P Congrats on your pregnancy!
