My baby at 8 wks 3 days! W a strong heart rate of 171! Hoping for a girl! I have two kids already one boy whose hr was lower and one girls whose he was higher! Fingers crossed! What do you think?! Ps I am amazed that this was an external scan! Technology has come so far since my last baby 4 years ago!
