Us baby feels like a disaster

I have 3 SK and I am currently pregnant with my first. Every time I tell someone I’m pregnant I’m met with either “Was it planned?” “Wow that’s so many kids” or “how do you afford so many”

This really pisses me off and it’s also so disappointing to hear. My husband and I have been married for a year and a half, we are both in our 30s and this is a very much planned pregnancy but I can’t help but feel like this time is being overshadowed by his kids. If we were a normal couple NO ONE would ask these things. Can I have anything just be about me for once
