This is just weird

So I feel weird. Idk how else to explain it. No contractions just some back pain from moving around the house. No mucus plug, or water leak. But just weird. I took my toddler a bath and now I can't shake this weird feeling. He's been super active since then I'm just sitting while my daughter plays but I can't stop feeling weird. I can't call my doctor cause "feeling weird" isn't a medical thing and idk if anyone has gone through this Im 35 weeks but I measure a week ahead and my first was born 39 weeks with just my water breaking.
