I had my 7 week ultrasound today! I got to see the cutest baby bean and it's heart beat! I went home and jokingly said to my mom "not having twins this time!" (They run in our family) and she told me 7 weeks would be too early to tell if I were having twins especially Bc one can hide behind the other. Is this accurate? I feel like the doctor would have been able to see 2!!
