8 weeks or 13 weeks?

[MNfl]

I am a first time mom so I always have a lot of questions about my pregnancy! My last period was August 27th and I haven't had bleeding or a period since then. I recently went to get an ultrasound at what I though was 11 weeks but the baby was measured at 8 weeks. The doctor asked me if I had any bleeding and of course I responded "NO!" I am a little confused as to if my baby is younger than I thought it was or if it might just be small. Is that possible for a baby to be a little small? My maternal instincts tell me that it is older than what the doctor said. My pregnancy has been healthy and I have had no problems with my reproductive organs in the past. I just need more info about this so the next time I go to the doctor I can have questions and maybe understand the development process a little bit better. Thank you.

Did they at least give you an ultrasound? Ultrasounds determine pregnancy from the estimated LMP so if you ovulated later than that could be why the baby is measuring smaller. In early pregnancy all babies develop at the same rate... they dont start growing at their own pace until about 13 weeks... but up until then they should measure correctly. If you got an ultrasound done did they see a heartbeat?

my last period was oct 1 so i taught that i was 7 weeks pregnant but when i did the ultrasound the baby measured at 5  weeks, very few ladies deliver on there due date that is why they say 2 weeks before or 2 weeks after the only thing you should be worrying about is that your baby is doing good and is progressing as he or she should. the ultrasound test from 2 weeks after your 1 day of your last period not the 1 day. anyways as long as you baby is good you should be happy
hope this helps
best of luck to you

Your doc is probably calculating from the time you ovulated and got pregnant then from your last period. If you calculate from your last period aug 27 you are 13 weeks wich is how pregnancy is measured, now if you calculate using ovulation wich is about the 7 or 8th of october you would be 8 weeks. Your doc is an idiot. You should switch because this can cause a  delayed expectancy date. Seriously consider a new doctor. Good luck!!

My understanding is that babies in the early stages pretty much grow at the same rate.  They don't usually start to vary until the middle to end of pregnancies.  My guess is you probably just ovulated later than you think.  That has happened to me before.  Best of luck and Congrats!!

You may not have ovulated when you think you did. That's the only thing I can think of!

I tested positive on July 27th. I was about 6 weeks at that point. But my last menstrual period was May 16! So if I went by my LMP when I tested, I would have been 10 weeks on July 27th. I went to the doctor on Aug 13 and they did an ultrasound and found the baby was measuring at about 8 weeks. They were really confused when I told them when my last period was. But I know how screwy my cycles were to begin with. Anyway, I have had 2 u/s since then and the baby is growing as expected and is measuring exactly where he/she should be!

Probably the baby is a bit little no need to be scard let the doctor do wat they have to do if u still feeel insecure ask as many questions as u can i dont mean to make u terrify or anything i went to the doctor last week and the sonogram is givin me another due date it seems as though my baby is big for its age i was like 8.5 wks and my baby had a heart that was beating u could see it and it had a head and the hands and feets were forming. so everyone pregnancy is different.
