First time mom

Okay I’m 37 weeks and I haven’t been feeling the best last night was the worse I was throwing up and before that I was shaking terribly it wasn’t cold where I was and I could barely breathe when the shaking started. I searched it up online and it told me that it’s called “labor shakes”, I’m very hesitant on calling my midwife because I call for every little thing I just want to know if this means something bigger of if it happens normally.
