What should i do

I really want to get pregnant but im not sure if i can support one? what should i do?

Do not bring a child into the world if you are not certain that you can take care and provide for it.

^100% agreed. This is a no brainer.

May I ask why you want a child if you likely will not be able to take care of it?

Are you really 16 and asking this question? hopefully your profile is just outdated, but i would say that 16 is not a good age to have a child.
