You poor thing! I'm so sorry :( I would go get checked... I know stress isn't good
When I am upset I get BH however you are quite far along so I would suggest going to get checked out just in case!
I'm gonna bump this...I'm not really certain that it couldn't but you may have just pulled some muscles by stressing your body out. I know when I get really upset my stomach and back hurt after from heaving and crying so hard.
Just try to relaxing and calm yourself.
Sorry you're having a bad day
