The last couple nights I wake up in the middle of the night in a total frenzy. My heart is racing, I’m extremely nauseous and have diarrhea, I have horrible horrible crippling cramps all over my stomach to the point I can barely move, sweating horribly, and the minute I take the blankets off I tremble and shake non stop. I have no idea what’s causing it, it’s always super random. I’m 38+4 and it just started around when I hit 38 weeks. Not sure if it’s pre-labor or just really bad anxiety?
