should i feel bad?

so my fiance and I have a 6 month old son. we both want more children but lately I find myself constantly thinking about it. I've been having those phantom kicks pretty much consistently for the past couple of weeks and I've begun to notice that o literally find myself hoping it's real. financially we aren't ready but I really want it. and I know he does too but he doesn't want it right now since we live in a two bedroom trailer. I guess my question is should I feel bad for wanting this so much?
