Baby not pooping

My baby is 6.5 weeks and I have questions! I’ll start with one... she is EBF and is only pooping once every few days and when she does it’s a massive blowout. She used to poop a lot more but this has been it for the last week or so. I called my doctors office and the triage told me it’s normal for babies to not poop for weeks at a time... so they were less than helpful.

Even if it is normal, (which I thought BF pooped more than formula?) she’s very gassy and I feel like her tummy has to be upset. So I guess is this normal? Anything I can do to help?
