I have OCD and I get those thoughts so often. They constantly go around in my head and make me so anxious. I try not to think about it, but of course that just makes me think about it more. I don't know what the answer is, but I'm currently trying Luvox to get rid of my OCD. I tried to talk about these thoughts with my therapist, but she kind of shrugged it off and told me to put the thoughts away until a later date. Easier said than done. But you're definitely not alone with these types of thoughts.
