Simple puberty questions?

okay so im 14 and my birthday is in 3 months. I am not going to say I havent hit puberty, because ive read too many things saying I entered puberty when I first started getting pubic hair. But I am somewhat a slow bloomer. I have some armpit hair not much and quite a few pubes. The for awhile I have very little pubes but recently they have been getting somewhat thicker. My testicles have gotten somewhat bigger from when I was young. my genitalia (if thats how I say it) Is still the same size. I have arm hair (average) but little leg hair. My voice hasnt deepened and that what this question is. I know that this is a shot in the dark but I would really like to know about when my voice will start to deepen. ( Ive heard all that humanist crap about being yourself W.E.) I am curious. I am not happy about being a late bloomer but I am still very social. I think I am somewhat delayed from my lack of exercise. During 5,6,7, and some of 8th grade I was lazy getting fat (chubby; I weigh 184 pounds and I am about 5'9') Only recently have I stopped being a nerd and getting out. High school turned my no life into a social life and now that im excersing I feel healthier. Thanks for the help. Answer what you can :)
