Frustrated, pregnant & can't stop peeing?

I'm only 7 weeks. Before I got pregnant, I will say, I already had a really weird/small bladder and even due to my anxiety I could stress out and make myself think I had to pee when I didn't so I would be up a lot, but this is different. I don't drink a ton during the day or evening, and for sure not a few hours before bedtime, but somehow, every single time I lay down to go to sleep, I get this over helming, I'm going to pee in my pants any minute now, feeling. Then I'll go and lay down again and it comes back about two minutes later. I've been up at least over 15 times tonight to the bathroom, for 2 hours straight. I'm completely exhausted and just want to sleep but can't because my bladder is going insane. Is this normal? Any tips? Or if it sounds a bit excessive, does anyone know if it could be N additional problem?
