Growth scans

I have been having growth scans to check babies weight the last few months.

Both times the baby measures ahead.

They say she is 40+4 days now but should only be 37 weeks. Both my last 2 scans taken 4 weeks apart match up to the 40+4 dates, which worries me as she could be too big to give birth too by time I reach 40’weeks my dates.

Am I likely to go into labour earlier? Thank you
