Hi Brooke,
you must have so many conflicting thoughts and questions right now with so many things to consider,
I thought that while you're waiting for responses from the community,
this article by Calie Wyatt (a young mother herself) might interest you.

If you haven't already done so, I would urge you to speak with your doctor and express your concerns and questions to him/her. You might find that having a "team" to walk alongside you through your decision making process, (and through your pregnancy should you decide) may be very beneficial.
Also one from our editorial team:
