I hope you are not pregnant, but after 6 weeks it sounds highly likely you are. So get in touch with planned parenthood, and they can help you with tests and with taking care of yourself, and with your options. And don't forget a 3rd option possible. Adoption. Gosh there is so many childless couples who would love to adopt a baby of a young healthy girl!

Getting abortion because OTHERS tell you it's sensible and that you have no other option, is not an exercise of "choice". That is giving in to coercion. Don't let immature adults in your life convince you that you "must" do it, just because THEY wish to make your pregancy disappear, so they can feel better. It's your life, your body, your heart.

p.s. Yeah, if you go that route, your family will find out and freak out, but there will be others who will support you and help you.
