Little pains like that are normal. Probably just your body getting ready :)
Yess I have the same problem im 15 weeks but its been going on for a couple weeks now the doctor said it was normal too get a little pain here and there since your joints and muscles are loosening up too make space just be careful if it starts too deel worse & take it easy you dont want too pull a muscle I did I now have a pulled lumbar muscle and the doctor said if I dont take it easy its going too get so much worse with the weight gain so she prescribed me extra strength tylenol & I have too go too a back class too stretch it and such with a chiropractor /:
Thanks ladies I was just worried. What about back labor someone told me that's what is could be?
