Gas or baby?

So all day I've been feeling like I have gas, around the pelvic area but when I try to let it out it kinda hurts so I don't know if it's baby growing or just some stubborn ass gas that doesn't want to come out. Usually when I'm laying down I can let it out easily but today it just won't come out. I'm 10w4d, is this normal or do I need to contact my doctor? Have any of you had this issue? And I'm a first time mom btw
