My little miracle

So last Wednesday I went into the ED for spotting. They tested my beta count and I was at 30. The doctor told me that he was 95% sure I was miscarrying and to follow up with my OB. I went in Monday for more lab work and my levels were at 30000+. I had my first ultrasound done yesterday. Baby is inutero with a heart rate of 116. We still don't know how I went from 30 to 30000 but none of that matters. My little bean proved those doctors wrong!
