Annie, ask yourself this question, and really take some time to ponder it: will worrying about something prevent it from happening? Worry is a useless emotion. It's not helping you in any way whatsoever, and is only making you miserable. If you aren't seeing a therapist about this, I highly recommend it. By the way, I disagree with your friends who are saying if you worry about something, it's more likely to happen. That's not true either, so forget about that. But your friends mean well. Stop poking and prodding yourself, stop checking your bowel movements, and no googling symptoms either. Focus on living your life to its fullest potential. I hope that helps.
