38+5w feeling like I’ve leaked but nothings there?

I’m 38 + 5 weeks and I keep going to the toilet feeling wet and like I’ve leaked but nothings there 😩 has anyone else experienced this feeling? It’s definitely not in my head because I’ve only just came across it. I’m wearing a pad so it’s hard to say if maybe I have or not and it’s soaked in? But seems like it hasn’t from what I can see.
