*Warning - Pictures** I think I had a miscarriage??

I’m on my “period” now and I just went to the toilet to change my pad. I noticed some large clots of blood that I have never seen before. I touched it and it was very firm like tissue. I was going to post a picture but I ended up flushing it down the toilet. I then googled pictures of miscarriages and it looked very similar. What are your thoughts?
