I'm a little on edge

So I am on bedrest for preterm labor. I'm 33w today. The past few days I have been having really loose stool, which came out of nowhere. And today I woke up and immediately felt restless. I tried doing my homework and couldn't even focus on that. I felt the need to clean my whole house. The restless feeling hasn't gone away. I just feel like I need to get ready, if that makes sense. Like I'm waiting on something to happen. I have an appointment today, so if anything is going on my OB will know. But idk. Did anybody else feel this way and there ended up being a reason why?

Our goal was to make it 3 more weeks. I'm hoping this is just normal nesting/third trimester anxiety.
