am I pregnant?

Me and my boyfriend had sex on the first of may On the 14th of may I bled a good bit wouldn't call it spotting as my boyfriends fingers were covered and when I returned home the tissue was bloody I put a tampon in and woke up the next morning to go get my pill as I'm only starting it(my first time taking it) when I got home and took out the tampon it just had brown on it as If im ending my period I continued to take my pill and still haven't got my period for this month did my pill just stop my period because it's my first time taking it and it's reacting with my body?? By the way he didn't cum in me I'm not stupid he pulled out about 30-40 seconds before he cummed and wanked for that amount of time which was approx 30-40 seconds 1 minute max please help a girl out?
