Hello everyone! We had an ultrasound, she said it's a boy ?, everything is good, all in normal range with no deviations, thank God ???? but she said it might be low placenta, but not clear at 26-27 weeks we will see, we need to go for another ultrasound. Should I worry about this? What should I do to raise it? Thank you for your answer.
