Hie everyone

On my last appointment with dr.. my due date was shown as 1st dec in USG...where as in today's appointment the due date got way too much extended... it changed to 13th dec.. should I be concerned about this? My dr dint say anything as such.. she said baby's growth is fine

Im not able to get my mind over this due date extension :( and seeing it get extend so much im kinda of worried about my baby's growth... as there is almost 12 days difference..

Should I be worried about this difference??? Has anyone else had gone through something similar?

Ps. My due date acc to last menstural date is 8th dec

Thanking you in advance
