Miscarriage or period?

Erika

I was having pregnancy symptoms for about a week, tender breasts, nauseous, etc. Then all of a sudden the symptoms stop and that day I start bleeding. I wake up the next morning and I felt a huge blood clot come out and it was the size of my pad and thick. While I’ve been peeing through out the day there is still a bunch of little and big blood clots. Am I miscarrying or..??
