I had an ultrasound today. Gestational age 30 weeks 4 days. By the way, I’ve been using this app day by day and the baby’s measurements are the same as in the app, even the weight — 1 kg 550 g. Does it match the app for anyone else? Also my baby has taken the correct position; literally a week ago it was breech, but today it’s already head-down. I’ll be asking the doctors to allow me to deliver naturally myself since I had a C-section 3 years ago.
