Bleeding a lot after anal

So yesterday after anal I was bleeding a lot I was going to make a sex video of him giving me anal but there was the blood it was really bright red blood it even went all the way to the front the same thing happens last time but I didn’t realize it was from anal sex I thought it was just my period last time but I wore a pad and it didn’t soak it the next day it went away that’s how I knew it was not my period my husband said your bleeding yesterday and didn’t want to keep going. I’m mad because it ruined the moment I was moaning it was feeling good we have done anal like 4 times already the first time he put just a finger and I bled then his dick even his dick had a little bit of blood and he said it even smelled like poop I think a little poop came out with the blood. I hate when something ruines the moment our moment he was going slow but by accident he moved and hit me hard with his dick in my ass I’m scared because I had caught it on video and saw it was a lot like bright red like period blood I was finally starting to do anal I had never done it until now that we did it like 4 times. I want to find a way to make it feel better like it was starting to feel good and I was starting to have an orgasm and I had started to finally start giving my man ass I had always said no to giving anal and he was so happy the first time I let him go in from behind and he was happy from seeing me moan and talk dirty during it. We have used lube but he thinks just with saliva it will go in easily. I will buy more lube and buy a but plug to be practicing. I’m worried because I even noticed yellow discharge in the video I saw I had yellow discharge
