We had our 13 week check-up today. The twins are doing great. Both measure 3 inches in length and their heart rates were 153 and 163. The detail on the ultrasound was amazing. We were able to count the bones in the arms and legs.This is Baby B. S/he was very calm and cooperative during the ultrasound. You can see the baby waving in the picture. Baby B brought the hands to the mouth a few times.

This is Baby A (the baby closest to the cervix). S/he was very active, doing flips and jumping. When s/he relaxed we saw the baby drink quite a few gulps of amniotic fluid, and then had the hiccups.
As for me, nothing has changed in the past couple weeks. I'm still horizontal and all day and taking the medication to help with the nausea and prevent vomiting. The doctor said this may lighten up in the next couple weeks. I'm trying to be optimistic, but she also said there is a chance this will not subside. We'll just hope for improvement in the next couple weeks.
