I'm trying to fight the urge of wanting a baby..?

You're entering that age where a woman naturally should become child-bearing, so it's not that uncommon. Something that might help, sit down and do the finances. When you calculate that a child costs roughly $30,000 to raise from birth to 18, and that doesn't include college, it may sway you a bit. Another thing that might help, is think about your relationship with your boyfriend. Do you want to make that stronger? How can you establish that relationship to build it to as strong as possible first, so any baby you bring into this world has two well established parents? Focus on him for now. And on you. Go to school, get a job. Do things that would keep you occupied. And while you're at it, enjoy the children at your aunts daycare as if they were your own, you just don't have to bring them home and stay up every night caring for them. You're getting the good part from them!
Hope that helps, and remember, it'll happen when it's right.
