When was the first time you heard heart beat?

Hi, mammies to be... I'm just wondering when did you first hear your babies heart beat?
I'm currently 16weeks, and I've had 3 scans and 2 midwife appointments so far and I have still never been given the opportunity to hear my babies heart beat. 
I've asked twice but I just keep getting told maybe next time! I feel like I'm missing out and they just aren't bothered.
