Accurate dating pregnancy ultrasound

This is the time from ovulation to the next menstrual period.

If your cycle is 35 days long, for example, then you probably ovulated on day 21.

Your doctor may change your due date based on the ultrasound measurement.

This is most likely to occur in the first trimester, especially if the date estimated by the ultrasound differs by more than one week from the date estimated by your doctor based on your LMP.

Everything went well, it's def another little girl! She was all curled up in a ball, arms and legs over her head, rolling around, it was absolutely adorable!

The doctor came in and said that everything looks perfect, the baby has everything she needs!

If you know you had your LMP during a particular week, your doctor can estimate your due date accordingly.Once you have a general idea of when you ovulated, you can use an adjusted LMP to find your due date with a pregnancy wheel.After you calculate your adjusted LMP date, simply mark it on the pregnancy wheel and then look at the date where the line crosses. Some pregnancy wheels may allow you to enter the date of conception — which occurs within 72 hours of ovulation — instead of the date of your LMP.In these cases, a pregnancy wheel can still be used, but some simple calculations will be necessary.The second half of a woman's menstrual cycle always lasts for 14 days.
