So I'm also 16 yrs old, and I have been late on my period this month, I am worried because this has never happened to me, I was suppose to get my period September 3rd - September 8th, and i still haven't gotten my period and its September 8th should I be worried, my boyfriend and I have never had sex together, and I have never had sex at all. So he is telling me that i can't be pregnant, but I also have been eating A lot and have been feeling tired lately also. He and I are both worried on what is happening, specially me. Can somebody tell me what's happening to me? please!
