Is this normal?

My sweet girl was born five days ago, my milk came in on the third day. It’s 2:50 in the morning currently and yesterday’s poopy diaper found was three, with one barely counting due to there not being a whole lot of anything other than pee. She’s had several pee diapers though. She’s exclusively breastfed and I was wondering if that was normal? I’ve heard tell that breastfed babies could go a while without pooping, but I didn’t know it was this early on. I haven’t been able to make a pediatrician appointment yet, so I thought I’d ask some other moms in the meantime. She’s also been fairly gassy, but has been passing gas with little to no problems and has been getting burped and doesn’t seem too bothered.
