Finger-sized blood clot?

My period started yesterday but it’s been really weird. It started off with heavy spotting for almost a whole day which has never happened before (I never spot before my period). Usually within the first 12 hours my period flow becomes pretty heavy but for some reason it’s been fairly light however with tons of clots. At first they were pretty tiny but then I had one that was literally the length and width of my ring finger!! I’ve not gotten one as big since then but when I use the bathroom it feels like there’s multiple clots with ever wipe and ranting in size from tiny to medium. Is this normal?? Please help!!

Ps there is NO chance of pregnancy, I am a virgin. I’ve had my period since I was 14 and now I’m almost 17, and my cycles are still irregular but this has not happened before!!
