Try not to stress. With my first the ultrasound was behind the due date according my my cycle. When I ask my OB he wasn't at all concerned said it happens all the time. They also predicted I would have a small baby (6 lb) In the end I delivered a healthy 8 lb 21 1/2 inch baby boy!

OB/GYN’s use a convoluted formula to predict due date unless you did IUI or IVF which is exact. Keep in mind that the docs calculate from the first day you started your period not the day it ended. With that in mind and assuming you do the same thing, if you had your period 8 weeks ago and ovulation occurs mid cycle, around day 10 to 15, then conception would have occurred roughly 2 weeks later than the start of your period, which puts the fetus at around 6 weeks.
Trust me on this, if there was anything wrong, they would tell you. They won’t instill false hope.

That happened when I got pregnant with my son. I was coming off the pill so I think my cycle was messed up. Regardless I didn't ovulate 14 days after my period which is what is "normal". He was measuring about 1.5 weeks smaller than what I estimated. Unless you are one of the people who has had a regular cycle forever and are 100% sure of the day you ovulated I wouldn't be worried. Also the doctor and ultrasound tech should be able to see if anything is wrong. If your only worry is your own due to the size I wouldn't think anymore about it. Relax and enjoy your pregnancy. It will be over before you know it.

Hey there! During my last pregnancy, the due date "changed" three times. They also estimated his weight at seven pounds, and he came out at 9.1! I wouldn't pay too much attention to it. If you know when your date was, just be prepared for an earlier delivery than the docs say :-)

During my last pregnancy my first ultrasound measured 6 weeks 3 days when I thought I should have been about 7 weeks 3 days. My due date changed several times. That baby is now a sweet little almost one year old! Congrats on your baby!

This is very common...try not to worry about it. Mine always measured larger than what should have been by my period.

I had the same thing. Granted, I have PCOS so my cycles are really weird, but I went in thinking I was a little over 6 weeks and was only measuring 4. I was shocked too! At 4 weeks....there really is not much to see. My doctor did another transvaginal 4 weeks later and the baby was measuring 8 weeks. Most likely your baby is fine!! There may have a change in when you ovulated. You could always call the doctor's office and speak to someone about it, just to put your mind at ease!

Please don't worry. You could have gotten pregnant anytime between the date of your last period and when your next one was supposed to start. 6 1/2 weeks may be right on target and if it isn't, you may measure differently at your next ultrasound. Lots of women measure one thing at one ultrasound and different by a week or so at the next one. Just try to relax and take care of yourself. Worrying about this will only cause you stress. If there is a concern, your doctor will surely let you know. Congratulations!!!
