possible miscarriage? advice please.

Kara

I've never miscarried before. My period was supposed to start around the 6th, but it never came. Pregnancy test give me too much anxiety, so I was waiting to the 1 month late point to take a test. On the 24th, I woke up with A LOT of blood on me and I figured it was my period, so I showered and went on about my day. I had severe back pain and unbelievable cramps. I went to the bathroom a few hours later and passed what I thought were big cramps. then today I passed this. (the picture) everyone I talk to says it's a miscarriage but I'm not sure about what I should do. the bleeding has stopped, but these glob looking things keep coming. Any advice welcomed at this point. ☹
