Minor Upper Chest Pain in Early Pregnancy?

Elizabeth • Mommy to Celine and Patrick ❤️❤️
So I've been having just a little chest pain, right above my left breast. It mainly acts up if I move my shoulders back. I looked it up and found something called dyspepsia, which is somewhat common in pregnancy and is mainly caused by heartburn causing inflammation in the chest area. 
I'm very early (4weeks 5 days), but I have been having quite a bit of heartburn. Has anyone else felt this pain before? If so, how far along were/are you?
