baby is growing

Kristine
Top pic is at 6 weeks and bottom pic is 8 weeks. Baby is big and hr is 167. 
Don't be jealous that I have extra ultrasounds. They only do this if there is a reason.😑. 
Just hope that the scare they are giving me turns out to be nothing. 
I couldn't really explain it if I tried. They thought there might have been a twin, there wasn't. Now they don't know what the extra mass of tissue in with the baby is. It's not pictured here. But I'm scared!
