The "cousin" situation is not an issue. First of all, you are not FIRST cousins, and--if you read the novels of Anthony Trollope--England, especially its upper classes, does not frown upon first cousin marriages as in some U.S. states.
In Britain, the legal age of consent is 16, so if Stevie is a Brit, living in Britain, then there will be no legal action.
I would say, either make an appointment to see a Counsellor via your school (are you still at school?), or via your G.P.
If you decide to keep the baby, then the father will be forced to provide financial support, via the Child Support Agency.
Tough situation.
Hope it all works out for you.
