My biggest problems and concerns with teen pregnancy are;
1) The financial difficulties that lies ahead for both mother and child. In this current day, the economy is reaching its downfall if it hasn't already done so. Money is an absolute necessity, and even without the economy money is something that is difficult to earn (in the adulthood world, at least xD). A teenage mother will find herself not only earning enough money for school/college in general, but also enough money for her child(ren). Both are exceedingly expensive, and require large amounts of income.
2) The immense trouble with the fathers and child support. One of the most common occurrences within teen pregnancy cases is that the father abandons the girl and the child. Although there are indeed fathers who stay द्वारा the mother's side, there are too many that eventually walk away. This will then lead to problems with child support, and the input that the father should be providing for his daughter(s)/son(s). There are millions of situations involving child support troubles in the United States alone, even among cases where the parents aren't underage. There's also cases where the baby could be left with a grandparent या relative, and it's also या just the mother who is failing in supporting her child. Child support-linked problems are a growing concern.
3) There's been studies दिखा रहा है that और girls who were born to teenage mothers are eventually following the same route, and become pregnant during their adolescence as well. I'll post a link here if I find one.
4) That the media may possibly influence this.
These are my concerns when it comes to teenage pregnancy as of now.
However, I still firmly believe that a teenage mother can find the strength, wisdom, and courage to raise her child, fulfill her life and overcome such a challenge in her life. And that the fathers can be good dads xD
