Baby's heartbeat.

Kristina • 3 early miscarriages. 1 stillborn to a baby boy in, momma to a baby girl & ttc ❤️
I'm 5 weeks and 2 days. 
I go and hear my baby's heart beat October 5th & I'll be 7 weeks & 6 days so basically almost 8. This is my third pregnancy. ( I had 2 miscarriages, one at 12 weeks and the other at 4 ) I asked my doctor if we could hear the heart beat earlier than the 13 weeks he origanlly wanted to do the scan. Is it normal to be so nervous and so happy all at once ? Hoping this baby sticks & is my rainbow baby ❤️
