I had unprotected sex 6days ago the next day I bleed some a little bit of dark blood and then nothing else I started my period the first of this month and ended on the 7th lately I've been throwing up feeling tired,I pee constantly, and getting dizzy(and I mean really dizzy) am I pregnant?
p.s. we use the pull out technique and I'm pretty sure he didn't pull out on time and no birth control. Am I pregnant

Impossible to tell over the internet, especially with such scant information.
