Wanted Pregnancy

This is kind of weird and I needed to rant a little. I'm only engaged and my fiance and I plan on waiting another year or two before getting married. And then we plan on waiting even longer before trying to have kids. I haven't said anything to him because it's so far in the future, but I've been getting such baby fever recently. Wanting to get pregnant, have a baby, make him a father..He'll be such a good one..I think about it almost everyday. It's only been this way for a couple weeks and I'm sure why. Just a strong and consistent urge to carry his children and start a family with him.
