Could I be pregnent?

I was suppose to get my period on May 3rd and I had brown spotting and on may 4th the samething when I wiped there was light brown. On May 5th I started bleeding. All week I've been really tired and when I eat I feel really full and can't eat much and feel like its ready to come right back up. My boobs started to hurt off and on on May 3rd. Could I be Pregnent?

if you dont have you period and you are sexual active then of course there is a chance you could be pregnant you should always use protection not just to reduce the chance of getting pregnant but the chance of getting a std you cant just trust anyone. if your that concerned...take a test.
good luck
