I am at eight weeks according to my u/s. Dating by my LMP put me at seven weeks. I had my first ultrasound six weeks past LMP and measured 6w6d.
The OB that was having trouble trying to get a good EDD based on the u/s and my LMP. She then checked me internally and said I am measuring bigger than 8 weeks.I doubt I am having twins because only one embryo was seen on u/s. I also don't have the classic weight gain and morning sickness that go with twins.
What can cause someone in early pregnancy to measure bigger than they should be without the possibility of twins? I am very definite on my LMP as I was on vacation when it started. I know you can ovulate early as well but would there be this much difference? Could this indicate a problem or can this just be normal for some pregnancies?
Thanks for your answer in advance.
If I am understanding you correctly, the ultrasounds are suggesting that you conceived early in your cycle. But the u/s 's are consistent with each other, so it doesn't sound like there is anything wrong with the baby. They agree on your due date.
As for the size of your uterus, hate to say it, but they do come in different sizes, just like noses or ears.
