17, and looking for advice.

So I don't know really what to do honestly and I need opinions or help or advice honestly. I'm 17, and yesterday I found out I'm pregnant. I have been on the pill for 4 years, and honestly I never expected it to mess it up, but it did. I took it timely. Im pregnant with my boyfriend of two years. Now, I'm not scared of him leaving or anything because when I told him , he supported everything and said he'd be working more for us. The only thing I'm scared of is telling the people I'm close to, especially since they never thought I was sexually active. I'm not sure what to tell them or when exactly. But I need any advice that can be helpful to tell them or any beneficial advice for this pregnancy in general.
