No just my vet's notes in my chart. lol.
I started it rather jokingly because I remember the OBN/GYN office telling me they could predict the sex by heart rate (this was long before the 20 week date of the only US you would have back then)....any way there is a noticeable difference in heart rates and honestly I've never timed it.
