Leaking ... thoughts? This normal?

I’m 35 weeks today. I feel like all day today I’ve been “leaking.” I go to the bathroom, and sometimes my pants are a tinge wet. If I’m sitting down or laying down I still feel it. I don’t feel like I’m peeing myself at all but could it just be me peeing since baby is pushing against my bladder? I’d know if it was my water right? I have had a headache since last night, haven’t slept well the past 2 days, and some occasional back cramps but that’s all. Is this normal? Happen to anyone else? I have an appointment Monday but figured I’d ask here first.
