Miscarriage or Paranoia?

Bri • Mommy to my wonderful Monkey, Bear, & Bug as well as my four sweet angel babies 💜 Taken by my soulmate and best friend 💍 Expecting #4!!! 👶🏻

I took a test last week and it had a super faint positive. I had gotten an appointment with my ob/gyn scheduled, but i started cramping pretty heavily Thursday and it just kept going. Friday was cramping and spotting, then early the next morning, i passed the mass in the pictures(sorry for that), and have been moderately bleeding since. I'm assuming the test was a false positive and I'm just over eager to get pregnant, but I figured I might as well get some insight as to what this is. I've never passed anything thats looked like this, in the past. I appreciate any help i can get! I've had 3 full term pregnancies, and a handful of miscarriages, but this just seemed different. Thank you for your help, in advance 💜
