Third degree tear??

Chelsea
Ok, so with my first child I had an unmedicated child birth with a third degree tear. My chunky girl was 8lbs 6oz. My question is has this happened to anyone else/ does anyone know much about it? I wanted to know if the risk of tearing again (or worse :) is greater if you already tore pretty badly before? Anyone have a similar situation? My daughter will be three in February and I am pregnant now, and just now thought to look up what exactly third degree is. And have scared myself to death. The next step up is a fourth degree, and I'm freaking out lol. Now I have an explanation for the little bump of scar tissue (I thought it was just a non annoying hemorrhoid) I didn't realize the degrees were the length of tearing but rather the depth of internal tearing. Sorry for tmi 😬
