Constant dreams about babies?

I've been dreaming about babies, children and pregnancy for the last two months. It's driving me nuts. Sometimes they're happy dreams, like the one where me and my husband (now boyfriend) are in the backyard playing with a little girl (around 3 or 4) named Lilah. There's others where I'm hemorrhaging and I can't get to the hospital, theres one lying on the couch 9 months pregnant and my boyfriends heads laying on my tummy telling me that we're going to have to stop the pregnancy, theres ones holding baby Logan after being born and crying happy tears. All of it is driving me insane. I even took a pregnancy test to see if that would stop it- but then I just dreamed of being at the doctors getting a test. I'm not pregnant. I'm 17 years old. I do want kids when I'm older. Is this unuasual?!
