i finally had my ultrasound yesterday -- that is a long 3 week wait-- and there was not only one heartbeat, but two!! I am still in shock! I am so happy. I have always dreamed of having twins, but we never had more than one embryo to transfer before now! I was so scared before the ultrasound that I was crying. I prayed and prayed for a heartbeat and God gave me two!! Heart rates were 138 and 142. A measured 7 weeks1 day, B measured 7 weeks. I was 7 weeks 2 days.  I am so very thankful.  Still very early. Praying for a healthy pregnancy!
