I agree. I mean, it's one thing to get pg when that young when you're not expecting it, it happens, but to "try" when you're THAT young? Sure, babies are cute and look like a lot of fun, but when you get no sleep and your baby is crying all the time, and all the trips to the dr for everything, well, at that age I just don't think she knows what she's in for. There's no way that a niece & nephew prepares you for parenting, unless you are their sole caretaker!
Here's my advice, for what it's worth. Get a puppy. If you can successfully raise and TRAIN (and I don't mean just the basic sit/stay/beg stuff) a dog without giving up or giving it away, then you will be much better prepared (although certainly not completely

) when it comes to having a baby. With Iria alone, I was up with her every night for the 1st 1 1/2 yrs because she couldn't hold it that long. And all the times she was sick, especially a few years ago when she was sick from Dec. thru Feb . . . that was alot of vet visits, and I had to use a baby monitor for her at night! I have to say I feel much better prepared for a baby than I was before we got our dogs.
