Difficulties because of her young body? I had my daughter at age 16 and my pregnant went fine!
Wouldn't of changed a thing about my little girl :)
I'll agree it isn't as I thought it would be but she's perfect and definitely wouldn't change her for the world :)
I don't recommend that you try to have children right now given your situation. Babies are cute, but they are also a lot of work, cost a lot to raise, will be a difficult pregnancy due to your young body, and will put any relationship through the wringer. Having a baby is not all blue skies and roses, and it is even harder outside the confines of marriage. Having kids now, you will miss out on the carefree times of your youth. You'll have plenty of time to have kids later, and in a better situation.
Yes, that can help you conceive. good luck
