I’m currently 33 weeks and 5 days today and we went to our baby ultrasound yesterday and they said baby girl was measuring on time, but her stomach is measuring a little over two weeks ahead. They also said she had a cyst on left kidney and that I had a lot more amniotic fluid surrounding the baby which is causing her stomach to be a little bigger. They are going to be keeping an eye on it and we go to ultrasounds every week now. Has anyone ever heard of this?
