thick vomit

Br
So today was my first time actually throwing up in my pregnancy. I have a really bad gag reflex when I'm pregnant. I decided to do a mid day brush due to a nasty taste in my mouth and started to vomit my whole life up. Weird thing is it was super thick like oatmeal thick and was actually kinda hard to get through my throat. It kept getting stuck and I was choking and the last thro up session I had to force it back down because I knew it was going to get stuck. Anyone know why it was so thick? Do I need more water or wat? My throat is on fire and it feels like it's still some in there.
