Possible miscarriage?

Helen
My period was due Wednesday and finally started on Friday. Usually, I only bleed a bunch for 1 day and some cramping but by day 2, I'm okay. My cramping is so bad, I took an rx painkiller. I'm also passing a ton of clots (photo below) every couple of minutes. This was all of 5 minutes worth of clots. This would be my 3rd miscarriage and I didn't even know I was pregnant this time....is there a way to test if that's possible without going to the hospital? I just cannot handle one more doctors visit right now.
