Back pains...

Brit.tanyyy👑 • Soon To Be Mommy👶🏻😘 20 Years Old👑. 10/29/2016✨
Been having a little back pain on my right side and then it switches to my Left side. 
I did pick up a case of cans but I don't think that would hurt my little one, would it? 
I have been extremely careful but I wasn't thinking about picking a 12 pack of cans. 
Would it hurt my little one? Could that be making my back hurt. I don't wanna lose my little one 😔 who else is 5 weeks and 3 days pregnant and having a little bit of back pains...
