Irregular bleeding

So I am a little stressed/ worried. I have been on my period since the 15th of this month and my period usually only lasts about 5 or 6 days. This one just has seemed different. It wasn’t as heavy as it usually is at the beginning and I didn’t have the bad cramping either. Ever since yesterday it has gotten super heavy and even thicker than usual like I’m passing blood clots. I have never miscarried but I’m hoping that has nothing to do with it. I’m just worried.
