Practical Suggestions
In terms of a practical suggestion, I came across an article that I think would tie in very nicely to the work you have done so far. I will include the link at the bottom of this post, but it is regarding the family influences on teenage pregnancy. I thought this could be a relevant section to add to the “causes” you have listed at the moment. I also thought it would create a stronger argument and provide some more peer reviewed evidence for the section on assisting adolescent parents and prevention. I really enjoyed your topic and I think you have done a really good job with the information you have collected. I just think a greater emphasis should be placed on the family influences, as the support system of the family plays a large role in almost every case of teen pregnancy. I also think this is a good addition to the causes section more-so than the prevention section, as many mothers who became pregnant as a teenager came from dysfunctional families.
Cheers!
Sorry, here is the link to the article I discussed in the post above ^^

And the reference of the literature is:
