having a baby

Le
I know being a mother is totally worth all the sacrifices and I want nothing more in life then to be a mother and have a family. But how do you know when you're ready? I know people get "cold feet" right before a wedding even though they know 100% that's what they want to do and I wonder if that's what's happening. I want a child more than anything but I also love the freedom of only worrying about myself right now. Me and my boyfriend decided on trying for a baby which gives us nine months to build our house and get our debt half paid off. I'm just worried about not being about to pay enough off in time and it never going away. I know you'll probably just say wait a few years but he's 28 already and Is finally ready also I'm only 19. I know what I'm doing so I don't want to hear any negative comments, I just want to know what you think. I was born to be a mother and want to be so badly, if always wanted to experience pregnancy and everything that goes along with it so is it normal I'm a little scared because its a huge commitment?
