Hey Our expert will help you soon thanks for asking qus.

Hey Don't worry, Your fetus develops at at different rates, because of which the estimated due date from an ultrasound during the second trimester is less accurate. You can follow the week that's mentioned in anomaly scan. Its 20 weeks for you

please consider the scan date as it is more accurate. So there is a difference of +/- 2 weeks and the EDD keeps changing as the pregnancy advances. So please ensure you with with the date of the scan
