Chest pains?

I will definitely go to the doctor if I can’t bear it but I just woke up with pretty bad chest pains. I’ve been having heart burn recently but this doesn’t feel like heart burn. Last night my stomach was hurting and now I just woke up with my whole chest hurting and a little up my neck. Has anyone experienced this before? I’m super nervous as I’m 20 weeks pregnant and worried about the baby.
