Pregnant-16-advice

I'm pregnant, 16, UK, and my parents are stern. This was not planned and completely accidental. My parents have no idea I'm sexually active with my boyfriend and honestly would kill me if they knew I was pregnant. As much as me and my boyfriend (18) would love to have this child, and as ready as we are, I have my studies and life planned. I can't keep it and I know that. How/where do I go about to look at my options?
