Natalie has a question

Hi there, I can't find anything out there to support this but do you think, or know of, any cases where a heart rate monitor gets wonky while you're pregnant? My last two runs my heart rate has jumped to insane #'s and then dropped right back to normal #'s just as fast, and yet I'm not out of breath or tired. Is there any chance it's picking up my baby's heart rate? Or is my heart rate monitor just broken?

thank you,
natalie

Natalie adds that she suspects this is impossible, but it has only started happening since she has been pregnant. Has anyone else ever experienced this? Are any of you heart monitor experts? Let's help a gal out. :)
