5 week postpartum

I’m 5 weeks postpartum and hubby is already talking about having another baby. I was planning on getting udi I talk about it with him he told me not to get because he was worried about side effects. Today he told me he wants another baby as soon as possible. I told him I wasn’t ready for another any time soon he just says to think it over. Has anyone had a boyfriend or husband that wanted a baby this soon? Why?
