I'm 36W and I've been like that for past week. I've been chugging water and snacking but I've been getting heartburn or can't keep it down at all. Just morning sickness love :( I had it the whole 9months with my daughter , thankfully with this pregnancy it comes and goes.
It sounds like morning sickness peaking it's ugly head again. Are you by any chance hydrated that cab cause dizziness and cramping.
