Was I wrong to call her a bitch in this scenario

So basically I was telling my husband yesterday how the day was a bust because we could’ve been at home. (His friends wanted him to drive an hour to pick them up, we drove, they kept postponing the time and then cancelled)

Anyways after I said that his sister says “then don’t have anymore kids” I was like “what does that have to do with anything that I’m talking to my husband about? And I’ll have as many as I like” then she said “then stop complaining” so I said “then stop being a bitch”

It just really upset me that she butt into our convo not even knowing what we were talking about. Then had the nerve to say something like that when it had nothing to do with what I was even talking about. We both have two kids and I stay home with mine 24/7 she only has one of hers 3 days a week and the other goes to daycare 7 days a week even though she only works 5 days a week. So how dare her try and shame me for previously venting about how stressful it is staying with them all of the time. It really hurt my feelings
