Upper back pain of spine

Nana
Hi, im in my 10th week (first trimester) and recently i feel permanent pain in the upper part of spine (between my shoulders). I haven't gained any weight yet and my belly doesn't show at all. I can't explain this pain but i think its still connected with my pregnancy thing.
Is there anyone with the same problem here? do you guys have any idea explaining it? or if you know anything about it then how long does it last?
