In so much pain?!😭😞

Heather
So today I made it to 34 weeks, went in for my nst and everything looked swell. .I expressed to my dr that I'm feeling a little bit of pressure down there and she said it was fine. I came home and thought I was gonna clean but didn't make it very far before I sat down from being so utterly exhausted. Now I'm feeling a ton of pressure between my legs, my pubic bone feels sore, my whole belly feels sore, my legs are killing me and the exhaustion is like none I've ever had. I also keep getting these quick bouts of shortness of breath and feel like butterflies in my chest..I wonder if that's what they call "quickening/lightening"? Any advice?
