Hello, according to the gynecologist my pregnancy is 39.6 weeks. By ultrasound it’s already exactly 41 weeks. The doctor absolutely refuses to agree with this date, although I specifically had an ultrasound 3 times and in all scans the gestational age is larger by a whole week. I would like to know at what gestational age labor should be induced? And can the gynecologist send me to have labor induced at 40 weeks, or will I have to wait until 41? Because then by ultrasound it would be as much as 43 weeks of pregnancy... and I’m worried. Thanks in advance
