I understand that making these hard decisions may be so hard because of the fear of getting judged by others or emotionally . I think that girls going through a situation as hard as this should be 100 percent sure of wanting to go through this and also getting well informed of all the risks that you can go through and also go to concealing before choosing a decision because its something very serious that can be traumatizing for you the rest of your life.
I respect everyones decision and think that being pregnet at a young age is not necsseary a bad thing things happen to everyone even if you are as careful as can be. Of course fear of rejection of parents can also be the cause of you wanting to commit this actions but parents eventually get over it. I have many friends that have gone through these experiences and they are either single mother or don't have support from their parents but they are tough and keep their babies and do great. Don't let fear or rejection push you to the wrong decisions
