First ultrasound

I had an ultrasound today. It was so uncomfortable having my bladder all full and then when I went in for the u/s the tech said that my bladder was too full and squishing the baby so she coudn't see. So then I had to go pee 200mls and then she could see the tiny baby. Then we did an intravaginal u/s so we could see better. The baby measures 6 weeks 4 days which is right on time. She said the yolk sac looked healthy. We could see the little heart beating away, 124 bpm, which is also right on target.
