Baby measuring bigger then how far I am ????

This has been on my mind

I had an ultrasound at 12 weeks exactly my baby was measuring 15w 1 d

Does that mean baby will come sooner I’m petite so just curious if baby keeps measuring bigger if I’ll go into labor sooner then due date or if they’ll induce

Also did it change your due date or did they leave it the same?

And did you consider yourself still 12 weeks or 15 weeks cause babys size

My mother in law for some reason don’t believe baby is measuring that much bigger
