Cannot sleep!!

So I have upped my fluid intake to the normal level because I was just not drinking near enough fluids throughout each day, and I seriously cannot stop peeing. I will pee and by the time I walk from the bathroom to my bedroom I have to pee again. I’ll be 16 weeks Friday. I can’t sleep because I have to keep peeing! Lol! Is this normal or should I ask my doctor to check for a UTI? I was already very prone to UTI’s before pregnancy. Or do you guys think it’s just my body flushing itself out since its finally getting enough fluids?
