Rib pain

Abby • Due February 8th with our first child! Beyond excited!
I am about 5.5 weeks along and have my first appointment on Wednesday. Along with bloating, sore breasts, backache, cramps and fatigue I am now having pain in my ribs. I have a really small torso so could this be from the pressure of my insides being pushed upward already? Btw this is my first pregnancy, my fiance and I are ecstatic!
