Pain and soreness down there

I’m 36+1 and all of a sudden I have some pain and pressure feeling down below. Last week I was already dilated to 1.5cm but today at my appointment she didn’t check me. But there’s just this weird feeling going on. I wonder if baby is moving lower..!? Eekkk my first baby came at 39 weeks exactly. I’m nervous this baby will be early too but the unknown is just scary.
