35 weeks and these symptoms?

Some of this might be tmi but every time I eat or even think of eating. Well even when I simply just wake up in the morning, I’m ready to throw up. My stomach is tight all of the time and it feels like I can’t eat a single thing. I have a lot of sharp pains down there and it feels like I can’t get very far without it coming and going. I also have been using the bathroom way more frequently and even waking up at night to go. My bowel movements are every couple of hours now. I also have back aches that aren’t constant but can last hours. Anyone else?
