hi,
I am on birth control and i missed two days of birth control so i took one of my first week and two of the second. I ended up having sex that night and the next morning. After the morning i noticed that there was blood on the sheets and the shorts i had worn last night but i wasnt bleeding that morning (thursday) that thursday night however i ended up starting to bleed and i have been bleeding since it has gotten pretty heavy and my lower back hurts and i have very little energy. It is now saturday afternoon and it is still going. I thought it could be spotting but it is pretty heavy like a heavy period on birth control. what did i do? is it my period? should i stop taking my birth control? its saturday so i cant see a planned preg place and i have just come back from college and dont really want to get my parents involved. can someone PLEASE HELP! im really stressed about this.

thanks
