Hiding pregnancy

I’m 18. My husband and I live alone and we both have stable jobs so please don’t think I’m hiding my baby because I’m ashamed because the pregnancy was planned. So, I don’t want to tell people I’m pregnant I don’t want my mom or his mom or people like imitate family knowing because I want to get to bond with my baby before everyone else is coming in and trying to hold him and take care of me and him. I want just a month to be alone with my child. His family calls me a slut because we got married and decided we could afford a child and that we both wanted one. He was the one who wanted to get pregnant but somehow I’m the one who trapped him for money. He does make a lot but I love my husband for him not the fact he has money. He thinks I shouldn’t hide the pregnancy. That I should just wait to tell people I had the baby until Im ready and if anyone is mad that he’ll handle it. What do you guys think? Am I being selfish?
