hi my name is arie j...im 18 and i recently had a period dec 31st and lasted until the 5th but i had spotting until the 8th. prior to that i had unprotected sex everyday from dec 14th to the 30th and my fiance ejaculated in me. After my period and spotting was over i had unprotected sex from the 9th until the 12th and he ejaculated in me. on the 13th i saw blood when i whipped after i pee'd and today (jan 14th) it seems as though i have anothe period..what is wrong?

just a little background info..
I was on the shot for about a year and stopped in April, then i was on the pill for about i month is august.

Could this be related to stopping birth control? Am i pregnant?
Please help me, im away at school and it would be hard to go to the doctor and im really nervous and worried. The help will be truly appreciated.
