Has any one ever got told that they are having a big baby and it came out smaller!???

I'm 38wks+5 days... I had an ultrasound on at my 37 wk check up and was told my baby weighed 8'1 already 😳 I was sent to the hospital this oast Thursday to have Prepidil inserted in me because doctor said since baby is measuring big already he wanted to try to help my labor process... well Prepidil has not helped so far (I'm still pregnant) lol

I go back to the doctor on Monday but what I'm concerned about is what if the baby is too big!! I'm scared that he won't fit and they will tell me I have to have a C-section! Also everywhere I go people ask me if I'm having twins or they say "omg your going to have a big baby"!!

So now I'm scared!!
