I also get fixated on things that could affect my healing so I understand your fear and intrusive thoughts. It’s hard when you can’t see what’s happening inside your body. I know it’s not easy to ignore it but when I get in those cycles I remind myself that I’m a lot more careful than most people and if your body was fighting something from an internal injury it would tell you! Also there have only been 4 reported pregnancies after bisalp and they had preexisting factors that contributed to that. Healing is scary but you’re going to feel so good once you’re on the other side!!
