Baby sleeping to long?

My baby girl is 3 months old .. she sleeps like 10 hours a night.. i’m able to sleep, get up, shower, get myself ready make coffee and hang out until she wakes up.. but I’m wondering if this is normal? She is eating good and gaining weight appropriately (a little on the chunky side lol) my concern is that most of the time when she wakes up she doesn’t have a wet diaper. Only after she wakes up and is up a few minutes then she pees. Is this a sign that she should be eating throughout the night? Or could it be possible she just isn’t peeing while she sleeps 😩
