Birth control missed period am I pregnant. SOS

I’m on birth control since October 2017. I’ve never missed my period but right now my period is late by 14 days. I use to have cramps and I thought that it was going to come but it hasn’t. These last few days I’ve had on and off cramps slight ones but still nothing. My throat is so sore today when I woke up and yesterday night I couldn’t sleep I had a terrible head ache. I’ve been taking the pills 100% correctly same time everyday. I don’t know what’s going on. Is there a chance for my period to not come at all!?!? It always comes and sometimes it may be late but not more than two weeks. Is there a chance of me being pregnant or is my period just not gonna come ??? I’m also very very cold and I get goosebumps
