Is measuring 7 weeks, 2 days and has a strong heart beat. We are much relieved. I was so anxious to see if there was a heart beat given our previous miscarriage. They were very kind and did an early u/s yesterday so ensure the baby was developing appropriately.. As we are doing CVS testing, we probably know the gender in about 6-8 weeks. please keep your fingers and toes crossed for baby bean!
