teen sexual activity

I am about to turn 17 and i am a female that’s in a relationship that’s about as healthy as it can get for teenagers, we’ve been together for almost 5 months and i feel very comfortable with him and we have already had sex once a few days ago and we used proper protection ( condom and birth control pill) and i’m very worried about the possibility to become pregnant even if it is a small chance. I want to be sexually active and i feel completely ready except the pregnancy part. Abortions in my state are legal up to 6 weeks and i know i can travel to get one but i only live with my dad and it is my worst fear to have to tell him. We are very honest with eachother but i have not told him im sexually active for obvious reasons but i feel like in the end he would help me figure o ur what to do. What are the options for me if I do end up becoming pregnant? I cannot have a baby this young and it isn’t in my plans for a very long time but at the end of the day I know eventually me and my boyfriend will have sex again before i turn 18. Is it okay for me to be sexually active this young or is it too risky and should I just wait until i’m 18? I don’t have any women in my life to talk to this about and i’m not sure if im doing something really bad or not.
