This was my 12 week sonogram done. Unfortunately our jelly bean didn't want us to find out yet it's sex yet besides the fact it's early. But the baby keeped on moving and wasn't staying still. This is a abdominal sonogram and heart beat was 163. My husband and I have a feeling it's a boy but others says it's a girl. We tried the nub theory but could quite see the nub. What do you think???
