Am I having a miscarriage?

Maybe I’m overreacting! But here’s how it started. I got on bc pills early January, I missed my period that month. I started feeling nauseous around the end of January. But then, I started spotting around early Feb and I started bleeding like really bad after a couple days, it was all bright red and pinkish and I'm like ok it's my period but it's been going on for 2 WEEKS now. I'm like somethings up my period can’t be going on for over two weeks

... then I started getting these really big blood clots and it looked scary. I just really want to know what’s going on.. I’m going to my doctor soon but I’m just wondering if any one knows if this is normal...
