If the crl measures at 22mm how many weeks along is pregnancy?

Based on the provided information, it is not possible to determine the exact gestational age using only the crown-rump length (CRL) measurement. Gestational age is determined by considering multiple factors, including the CRL, fetal development, and other indicators. For a more accurate estimate of gestational age, it is important to consult with a healthcare professional and consider additional factors such as the woman's last menstrual period, medical history, and ultrasound findings.
