Baby measuring big

🎀Ric🎀 • baby#2due 7/16/ married to love of my life/ vegetarian/ pro choice/very uncomplicated/candid/blessed!🎀
I went to an ultrasound and was told the baby is measuring big, if I go with my last period day I am 14+2 but baby is measuring 15+3 which has now moved my due date. Has anyone gone through this? does it mean anything??
