chest pain?

Kaitlyn

I'm 8 weeks today and tonight, i just started noticing a pain in my chest. not like heart pains or anything but like a tight muscle. if I stretch my arms out like wings then bring them in to hug myself it's like a dull pain all over. could this be from my breasts getting larger or should I be concerned? I already have a large chest so it's hard to tell if they actually are bigger. thanks in advance for any advice
