I need help.. I maybe in seriouse trouble?

So I am 13 almost 14 and I havent started my period in almost 5 months now. There is no possible way I could be pregnant because I am a virgin. I have a problem. I have not told my parents that I have started my period Yet and I started a year ago. So I can't go to my parents for help. Another thing my boyfriend Is it possible to get pregnant if a guy had sperm on his hands then put his hand down my pants (if u kno what I mean) I dont think it is but not sure. I need advice fast. I am scared and completely alone on this):
