AM I PREGNANT ???????

Ok, so here’s the thing, my last period as you may see was on June 2nd. It lasted 5 days (as usual). I’m on birth control BUT I have to admit I have skip the pill like 2-3 times. On June 22 nd I got my period, AGAIN! It never happened before. And as I said it usually last 5 days but it’s been almost 10 days, oh and I have to mention I’ve been having cramps and my discharge is very dark. My cycle was regular all the time until now. My question is, is there any chance I can be pregnant??? (I don’t have much knowledge about pregnancy and or the symptoms) or in can be a problem with my insides??
