Am i pregnant? or are my hormones going crazy?

okay so... i've been seeing this guy for a month or so, we had the first couple times with a condom and everything was just dandy.. one night i was really stupid and let him go unprotected for just a few minutes...i freaked out the next day and took the plan b pill.. the next week i got my period only a week after i already had my period. ( causes of taking the plan b pill). its been about 3 weeks or so and we've had a few times without a comdem but only for 3-5 minutes and hes never ever gone in me (we used a condem everytime but what would ya know... they broke everytime) soo now im experianceing all of my period symtoms again.. cramps, acne in the T-zone area and i've been in a terrible mood for the past day... i got my period yesterday.. i wouldn't say its spotting bc its much more than that but i just feel like i shouldn't be getting my period after 2 rounds of the monthly fairy in the same month... also i was told my hormones could just be wacked bc i didn't have regular and now all of a sudden im doing it every night.. i dont know what to think...help please! i'm not ready for any of this!
