Pregnancy pains

Hi all! Just wanted some advice from more experienced mommas.. I’m 13 weeks and I expected all the normal pregnancy pains (mild cramps, pulling feeling, pain in my sides, back pain, etc) but what I was not expecting is pain in my chest. It happens randomly - yesterday it was happening when I laughed and today it’s under my left breast bone and goes all the way around my shoulder blade. It’s usually not consistent but has been happening often. Is this normal? How to I differentiate between what’s normal and what could be abnormal at this point?
