Can’t get enough sleep

Hey all, just found out in pregnant with #2 a few days ago but I cannot get good durations of sleep. I keep usually waking after 5.5 hours of sleep, having to pee. Then I am too excited to fall back asleep. Help? Is this normal? I usually can get little naps during the day as well but I’ve just never had this happen to me like this. Usually I get 7-8 hours straight sleep.
