Morning sickness and then some

This is my third pregnancy, our rainbow baby. I am sooo sick this time though. Boobs have doubled in size and hurt like you wouldn’t believe, I have almost constant nausea, some vomiting and I will go without pooping for 2 days then have awful diarrhea for 3-4 days. The cramping is getting work in my lower abdomen and I’m think it’s from constipation and gas.

Is anyone else having this??

My OB can’t get me in earlier than my scheduled appt in 2 weeks and I REALLY don’t want to go to urgent care.

Any advice??
