Pregnancy Wheel

Sometimes things happen, and you might find yourself being told that your due date is really a different date than you originally expected. Here is what you need to ask before agreeing to a change in date:. Most practitioners will look at a variety of factors as your pregnancy progresses to ensure that your due date is still accurate. Some of the things that are calculated into this clinical decision are:.

Other examples of things that might alter these readings would be the discovery of a twin pregnancyuterine anomaly, maternal weight, etc. One common scenario is that a mom has been told that her due date is a certain date her whole pregnancy, but then at an ultrasound near the middle of pregnancy, she is told a different date, usually only a matter of days different.

But the truth is this change, if it is less than 14 days in either direction, is probably within the normal variation, because ultrasound at this juncture is limited in its use for dating a pregnancy.

The specificity of ultrasound dating a pregnancy varies with each trimester with the most accurate dating in the first trimester which will vary plus or minus seven days and least accurate dating in the third trimester.

While being due a few days earlier might seem like a sweet deal now, it may be something that worries you if your pregnancy extends towards 42 weeks. This type of change might add extra risk to your pregnancy by facing an induction of labor that is unnecessary.

Ultrasound in the first trimester is considered to be much more accurate for dating purposes, but it is not recommended that all mothers have a dating screen because of such a slight difference in dates.

This is used for women who have no data or very scanty data from irregular cycles. Most of the time an altered due date will not immediately affect your prenatal care. The alteration potentially comes at the end of pregnancy when looking at intervening to end a pregnancy earlier because of the new due date. If you do decide to go with an amended due date, this is something to remember if it comes time to start talking about induction of labor.

How to Use Pregnancy Wheels to Calculate Your Due Date

One of the best ways to avoid changes in due dates is to ensure that you have the most accurate data upfront. When we look at a due date that is derived from your last menstrual period, we consider this to be plus or minus 14 days, meaning that we expect that your baby will show up between weeks 38 and 42 from the date calculated.

The average length of gestation is days from conception, often reported as from the last menstrual period. This may not always be true. If you do not know when you ovulated, you can also consider using the length of your cycle and counting backward 14 days. This says that you take the first day of your period and count backward three months, and then add seven days. So if your period started on February 1st, you would count back three months to November 1st and add seven days for a due date of November 8th.

So for someone with a day cycle, a good guess for the date of ovulation would be day 18, which would alter your due date by four days. While four days may not seem like a lot of time at the beginning of your pregnancy, it may mean a lot of time toward the end of pregnancy when looking at whether to do an induction of labor or wait a few more days. Never hesitate to ask questions about a due date change.
