Labor or sick??

I’m 35 weeks today, but something has been going on for the last 2-3 days. He has dropped tremendously and it feels like I’m squishing his head in my pelvis, I’m having random cramping in my lower stomach, I threw up twice yesterday (I haven’t been sick my whole pregnancy), I’m so exhausted I can hardly function, then today I wake up and just do not feel good. I can hardly make myself get out of bed cause I just feel like crap. I don’t know if I need to be watching for labor or if its just pregnancy or even if I’m getting sick, but I’m miserable ☹️☹️☹️
