Had our 3rd u/s today and we heard the heartbeat! 120bpm which doctor said was perfect for almost 7 weeks. And our burning question has been answered...it's definitely just one baby! DH is thrilled- he really was scared at the idea of twins.
MIL went with me to the appointment and she was so excited; it was great to see her so happy. I have another u/s on Friday and DH will get to go- it will be his first time to see the baby.
