Why am I always hungry after eating meal/s? Pregnant?

I am 16 and female. For the past week or 2 I have been constantly hungry. I eat a lot but don't usually eat 3 meals a day, e.g I miss breakfast but eat a lot of lunch and sometimes I don't bother eating dinner or vise versa. Today, I missed breakfast but I ate a lot... 3 bowls of white rice, several bacon and an egg and while I was eating my stomach was rumbling but was not making any noise. 1 hour later after eating, it started to make a noise while rumbling. It just feels like I need to eat non-stop. 

For this month, I started my period on June 1st and ended June 5th which was yesterday. My period was very light. On the month of March and April, I took a month of contraceptive pills and didn't have a break from it for two months, but then I stopped taking them on the month of May. And as I started my period on June 1st, I started to take them again then. While I wasn't on the pill, I did not have sex. Although, me and my boyfriend just did some oral. I'm a very OC person, so SOMETIMES whenever he touches me, I tell him to wash his hands, but not all the time. And whenever he came, I don't let him touch me. Although, I'm scared because he might have touched me (or probably just my underwear) after he came but he wiped his hands with a tissue. I'm just paranoid about all these. Please help. Could I be pregnant?

Thank you
