I just can't stop sleeping .

So all my pregnant friends warned me about the whole "not being able to sleep once you're further along in your pregnancy " well I've actually been sleeping ALOT . I sleep through the night (still get up to pee but go straight back to sleep) and when I wake up in the morning I'm still tired and end up napping an hour later. I nap maybe 3 times daily and still can sleep at night. It's so weird lol I've never felt this tired, I'm 35 weeks and this started around 33-34 weeks, anyone else been sleeping a lot ? Is it normal ? 😂
