Anal sex

So we tried anal last night and I had blood. I think we didn't use enough lube but anyway when I pooped now twice I have some fresh looking blood. Should I be worried or will it heal? I'm not used to anal at all and I wanted to try. I think it's just a tear like I've read on here that can happen but I only bleed when I poop, it didn't hurt to go but I don't ever want to do anal again bc of this 😔 sorry I sound dumb but I never had this before when we would try anal
