This is because we can use this landmark for all situations including IUI pregnancies; for Day 3 embryo transfers and Day 5 embryo transfers ; and frozen cycles as well!
Just subtract 14 from your date of ovulation. This is your "corrected LMP" last menstrual period. The reason we do this is simple - it's because textbooks assume the follicular phase is exactly 14 days! Once you know your corrected LMP, it's then easy to use this as the anchor, based on which your OB can calculate your gestational age.
Let's suppose your LMP was 5 January; and your egg collection was done on 24 January let's assume you took a long time to grow eggs ; and your embryo transfer was done on 29 January Day 5 transfer. This means that even though you are only 14 DPO and your embryo's age is only 14 days , he will calculate your corrected LMP as 10 Jan date of ovulation, 24 January, minus 14 days - which means your clinical gestational age or menstrual age will become 4 weeks 28 days!
Once you understand this "2 week gap" and the rationale behind it, you'll find it much easier to date your pregnancy! The way labs report hCG results just makes matters worse! Ultrasound scans are another minefield. While the sonographer can measure the baby very precisely, and the machine uses a computer to calculate the age of the baby and based on this, it reports your expected due date , please do remember that even though the ultrasound machine uses a computer to do its calculations, these are only estimates, and not as precise as the date you calculate based on the date of egg collection!
Irregular periods and fertility therapy can sometimes make figuring this out even more challenging. At University of Mississippi Medical Center, our fertility specialists are constantly trying to figure out how to provide clearer and better care, which is why we created this due date calculator. Simply enter the day and the month in the category that describes the best information you have on how you got pregnant.
For spontaneous pregnancy without monitoring or intervention , although the first day of the last period is the least accurate estimate of when you ovulated, it is close enough for many people. You are most likely to have an egg implanted on your ovulation date , which takes place on 14 th day of your menstrual cycle. A typical pregnancy lasts around 40 weeks , counted from the first day of your last period, or 38 weeks from the day of egg implantation. So, if today was 27 th September , and the first day of your last menstrual period was on 9 th July , you'd be 11 weeks and two days pregnant.
You can find more calculations on this topic in our conception date calculator. Although today we can quickly assess due date or pregnancy week to the mostly likely day, most children are not born exactly on their due date.
The average 5-week time span means that your baby may arrive anytime between week 37 and week We try our best to make our Omni Calculators as precise and reliable as possible. However, this tool can never replace a professional doctor's assessment.
