Passing crazy looking stuff after Ectopic?

Lauren • Ectopic Pregnancy 01/2019 💔 👼🏻 up above // TTC#1 since 07/2018

I was given methotrexate on 1/15 to end an ectopic pregnancy (pregnancy of unknown location) and I’ve been spotting for a few days but today I started actually bleeding like a heavy period and I lost this “clot” or “tissue” if you will. It kinda looks like the shape of my uterus/ovaries? Kind of scared. The pad was on for about 2 hours when I took this picture. Should I call the ER or is this normal??? 😳
