Might be too early...

But this is from yesterday. Went in for a quick check up because things had happened and we were worried and they did an ultrasound. Baby measured 15/2 and new edd is March 12, 2016. So baby is bigger and healthier than I thought! In that case, they took this, I'm wondering, is it still too early or is this quite accurate? They estimated a boy!! I'm so excited! We wanted a baby boy since before we even made the decision to make a baby :)
