Why have I had my period for so long?

I've been on my period for about 6 weeks straight now, and I'm not sure if i should be worried. I'm 16, and I've always had a pretty regular period especially after starting to take birth control pills. For about a month, I had been semi irregular with taking my birth control which has never really been a problem in the past when starting to regulate again. But, this time when I got my period ( after taking my birth control regularly for about two weeks to a month) for the first few days I was more heavy than normal and then i went back to a regular, not too heavy, not too light period. After having my period for three weeks i thought "okay, maybe this is just my body getting itself used to birth control again" even though this was abnormal in itself. I'm sure that this will be asked, yes, I have been sexually active. As of right now, i have been on my period for about six weeks, and I'm not understanding why. Should I be worried? What are possible things that could be going on?

You need to see your doctor.  A period should never last longer than 7 days.

Also, at first after going through my regular cycle, i had slight spotting like i usually do, and it gradually got heavier and went back to a regular period flow about two or three weeks ago.
