Pendulum predicted multiple times that I am pregnant?!?

An acquaintance of mine is into pendulum predictions. She has done several for me the last few weeks, and always predicting that I am pregnant!! This is a possibility. (unprotected etc.) But, a couple weeks ago, I bled for about 4 days when I was expecting my period. IDK if it was my period, or implantation bleeding or what. Well, I still have it in my head that I am pregnant, but all the home hpts I have taken come back negative. If I am pregnant, I would be about.....6 weeks?? Do you think it's possible or probable that I am?
