fetus measuring small?

[jnett]

I had an ultrasound last week which measured my baby at 6 weeks 6 days.  According to my last menstrual period, it should have been 8 weeks (so one week off).  I have longer menstrual cycles, so it could have been a later ovulation/conception...?  Has anyone else measured smaller than expected with good results?

just curious if u have any updates? I have just had my first scan after IVF.. so dates can not be wrong... and baby measures one week too small, but has a heartbeat. our doc basically told us she doesnt expect it to by next week. can they be wrong?? I HOPE SO!

Thank you. I hope that's what it is. I have not had any blood work done. I haven't had any bleeding or cramping so I'm still hopeful.

So much depends on your cycle. It is possible you ovulated late. I used to have a very irregular cycle (my daughter was born in July 1990...my LMP before I had her was August 1989!) so it is very possible that you ovulated late and you are not as far along in your pregnancy as you think.

Has your doctor done any blood tests to measure your beta hCG levels?

I went last week 11/3/11 for my first ultrasound. From my LMP I was suppose to be 9 weeks. The ultrasound showed the baby at 6 weeks and only measured at 5mm. I was told I miscarried. The next day I got a call saying to come back in a week for a second ultrasound because my dates could be just way off. There was no heartbeat detected. That would have to be almost 4 weeks difference. I'm still awaiting for this day to come to see if I have miscarried again or not. Oh, I miscarried in April. I'm expecting the worst but hoping for the best. What can the chances be that I'm a whole month off from my LMP? I'm praying I see a heartbeat on the next ultrasound.

Hi all. Just reading the comments and I see it was started a while back but figured someone may still be checking the board. I am almost 20 weeks pregnant and baby is measuring 8 days small as of May 9th. Baby only measured 5 days small last u/s and before that 3-4 days small. Went to a specialist and found out that my test came back + for trisomy 18. The u/s showed no signs of this except small size. Had a hot spot in her heart but they say that is pretty common. I go back for u/s on Tuesday and I am pretty nervous. Anyone have this happen? Any other reason for baby to be getting smaller if dates are 100% accurate?

Hi everyone
the same thing happened to me last april and i was pushed into a DnC and ive never forgiven my self since as now id never know. i swear i was only 5 weeks but cause they think they know it all they hounded me to have surgery, my point is i think we know in our hearts and following your own instinks in matter's  like this is the best way sometimes.
take what they say into account of course but if its not ment to be then i feel your body will rid the baby its self, i certianlly would never go for a d n c again.
