How To Properly Use Your Conception Calculator

When you properly use a conception calculator, you can accurately predict the date your baby will be born. A pregnancy will typically last 40 weeks – 280 days – calculated from the first day of a woman’s last menstrual period. This general guideline is just that – an estimate – because every pregnancy is unique. Some babies arrive early – other are later than expected.

Fertilization of an egg and implantation of an embryo in your uterus will take placed 14 days before your next anticipated menstrual cycle. When you miss your scheduled period and discover that you are pregnant, always begin regular checkups with an experienced prenatal medical doctor throughout the entire course of your pregnancy. Through prenatal care, you and your baby’s health will be consistently monitored. Any potential medical problems will be detected and corrected before becoming serious.

IVF Conception Calculator

Your In Vitro Fertilization (IVF) Conception Date is much more accurate than estimating a natural conception due date. When you undergo an IVF cycle, you can calculate a much more precise conception date for your baby because you will know the exact date of your embryo transfer.

Not only can you calculate your conception date, you can also estimate your baby’s prenatal development and due date based for each trimester. You can even pinpoint your prenatal testing dates!

Baby Due Date Calculator

After your IVF procedure – the date of embryo(s) insertion into your uterus – you will wait for approximately 2 weeks for your pregnancy to be confirmed by way of a blood test.

  • 40 weeks is only an estimated gestational age because babies can be born within a 30 day window of this date and be healthy
  • Normal term gestation is generally recognized as between 37 and 42 weeks
  • Only about 10 percent of birth mothers actually have their babies on their calculated due date

Multiple pregnancies achieved through the IVF procedure may produce special considerations concerning your upcoming IVF due date. Because there is a chance of multiple pregnancy when more than one embryo is transferred via the IVF procedure, you should be aware of the following typical gestational periods if you become pregnant with more than one baby:

  • Twins ~ 37 weeks
  • Triplets ~ 33 weeks
  • Quadruplets ~ 31 weeks
