I Got My Right Bottom Wisdom Tooth Pulled And The

I got my right bottom wisdom tooth pulled and the tooth that sits in front of that one pulled four days ago.Well I took a nap today and I woke up with a lot of blood in my mouth and I put gauze on it and I look inside my mouth and now I see where they extracted my teeth looks like a clot just hanging there it still looks attached but it's right at the hole where it was extracted. Just wondering is this normal?
