Is it possible for a sonogram to be 20days off? adult content

I am exactly in the middle of two dates I could have conceived. Wishful thinking probably... but has anyone ever had a sonogram be wrong as to how far a long you really are? By 2 1/2 or more?

  • Yes it is possible, the later in the pregnancyyou have your first sonogram the harder it is to predict the expected due date.  2 1/2 months would be a stretch, but 20 days is possible.

  • Actually I had a sonogram and it was accurate to the day. I didn't think it could be that precise.

  • I'm certain mine was 10 days off. I don't know about being that far off, but I suppose it's possible.
    We were charting, and my periods have always been out of whack. I'm positive I conceived 10 days earlier than they said I did, and they said my son, who was 4 days "early" looked late by his lack of vernix and long fingernails.

  • It's a guess, not an oven timer.

  • The later they do an ultrsound, the harder it is to figure out the exact due date. I had an utrasound done with my 3 year old at 36 weeks it the ultrasound came out to her only being 32 weeks! Its all on how fast your baby develops. She was born at 41 weeks and had infant apnea. The doctors told me the 36 ultrasound was actually probably right. She seemed premature.

  • Just wondering - do you need to know this because it could be two possible dads?

  • It's possible. A sonogram can't be exact, nothing can. It's more of a rough estimate. Good luck and congrats.

  • Could be. Not an exact science.
