i'm 17,Period for 2weeks,had sex,dark brown spotting for 2 days,no period. do you think i'mPREGNANT?

i had an unusually long period, for abotu 2 weeks nonstop, then i stopped around the 23-25th of march. then on the 19th of april i spotted dark brown blood, then it slowly decreased over the next two days. after that, no period. had some thick pasty discharge a week later, but now i'm all dry. no headaches, no back pain, no cramps, nothing. but a few days ago i had some pulls down under but it quickly went away. i did have sex on the 12th of april, with a condom. but while we were making out his genitals did touch my vagina abit, but he didn't go in and we were dry. i recently got sick, then on the 30th i got the flu and cough, but it's getting better. so now i'm wondering, am i pregnant? i'm really worried. please help.
