11 weeks and a trip to the ER

Sarah
I had to go to the ER yesterday after I slipped and fell hard as hell at work, knocking all the air out of my lungs. I was all cramping up afterwards and freaking out , but thank god everything is perfectly fine and I got to see the little lime dancing around in the ultrasound ❤️
I don't really understand the nub theory though, does it show in this picture ?
