hello i am 21 year old female. i had protected sex with a condom that had spermicidal lubricant on it. i dont think the condom broke as well. it was 5 days before my period. my cycle is usually 26 days. my period was regular for the first full 2 days and then some brown spotting on the 3rd where it usually doesnt start spotting on the 4th day and finishes up on the 5th. am i pregnant ? it is making me nervous. i also have been a little stressed from midterms this past week.
