This gem

I hope that this is the right place to post. I am 15 (16 in October) and I need some advise. A week ago I found out that I am pregnant. I had a two tests and ultrasound done and I am in 8th week. Abortion is not an option. I could never do it. I'd feel like I killed my child. My boyfriend promised that he will care for me and our child. He is the most loving and caring person I met in my life and said that he will be with me no matter what but I lied to him about my age and I am scared that he will leave me when I tell him. I told him that I am 16, that's over a year ago now and he thinks that I am 17 nearly 18. He is 28 and he's my soulmate and my best friend, I love him and I don't want to loose him. My parents don't know yet that I am pregnant. We decided to tell them in two weeks time when my bf comes back as he is working away from home. I fear talking to my parents the most. I was always scared of talking to them. I fear the worst from them and if I could I'd rather to never tell them. I want to continue going to school for as long as I can but I don't know how pregnancy will affect it.
