Advice please?

Okay ladies. This is my third pregnancy. I’m 26+ weeks and I’m MISERABLE. I’m working part time, but honestly don’t know if my body can handle it. I worked throughout my first two pregnancies and this one, I just don’t know if I can. I have EXTREME nausea. All the time. I have pain in my hips and pubic bone. I have hemorrhoids that are unbearable. And I keep having contractions. If you had that, would you throw in the towel? Or is it just me? I would like to say I’m overreacting, but I honestly don’t know if my body can take it!
