Teenage abortion

I recently got in a mess with my partner. I’m 17 and there’s a chance I could be pregnant. I was thinking about my options if I was pregnant; like abortion, keeping it or adoption. So much in me would want to abort it but my morals are telling me to keep it. My life is great. Why did I decide to ruin it by getting pregnant? I don’t know. I don’t want it to change. What do you guys think and what do you think God would want?
