Red dot rash from vomiting??

Question

I'm 15 weeks pregnant and although the nausea has subsided, I still randomly vomit sometimes, only worse. The past two times I have gotten sick I was left with this rash along my jaw line and neck that appears almost immediately afterwards. It also appears around my eyes slightly.

Now my jaw line and neck are very sore and my throat feels sore and swollen. Is this just from throwing up so violently?
