Is this normal?

My husband and I just got married in January. I'm 21 and he just turned 23. We've talked about trying to have kids in a few years, but some days he can be really wishy-washy. He can wake up one morning and talk about how we should try having a baby and how I should stop taking the pill and then a few hours later take everything he said back. It's really confusing. I always ask if he wants to seriously sit down and talk about having baby whenever he's like that, but he never really wants to talk about it. Does anyone else deal with this?
