When did you hear heart beat??

Elle • Trusting in God's timing while hoping to uplift others. Baby #1 with Jesus. He's not finished with me yet.
I'm 6 weeks today (was initially told 7 but then my baby was measuring smaller)...and at my 6 wk or 5 week ultrasound we didn't hear the heart beat. Was wondering when you heard your baby's heart beat?? Thanks!!
