33 weeks today

I’m 33 weeks and been having a lot of pain in my hips and lower back. Baby dropped last week and I lost my mucus plug. Yesterday the dr said I was 1cm and showing signs of pre term labor. This is baby #3 btw. As of right now I’m supposed to go back to work the 18th over the virus, I’m a hairstylist so will be on my feet all day every day without being able to rest. I’m at a loss on what I should do, any advice would be great. Oh and I just have this feeling that baby will come early and soon. It’s just like I knew that she was a girl before they even told me.
