Yeah I agree with Hannah, have a pregnancy test first so you know if you are pregnant or not before worrying yourself about what to do with the baby.
On whether to keep the baby or not if you are pregnant, it is entirely your decision. Whatever you decide in the end is the right decision for you, so don't regret anything afterwards. Just think about it a lot before hand, so you feel that you made the right choice.
And I'm sure you'll get support that you need whatever you decide.
