Calculate BF with our pregnancy calendar: what week are you in?

To work out how far along your pregnancy is, you need to know the first day of your last period. Baby Journey's pregnancy calendar can calculate BF automatically based on this, so once you've added a dot, we can be the first to give you an approximate date to work from and give you the answer to when your baby will finally arrive. If you want a little more understanding about how to calculate BF in practice, you can count months (counted as 28 days) or weeks of pregnancy (7 days) from the first day of your last period onwards - then you can figure out how far along you are. You will probably realize that 28 days times 9 (the number of months you are pregnant) is not equal to 280 days that a pregnancy is always counted as. This is because the 9 months that people usually talk about pregnancy being, starts counting from week 4, which is about the time you can figure out that you are pregnant. This means that you will actually be pregnant for 10 months if you count from the first day of your period! Calculating your due date will give you an idea of when the baby will arrive, but very few babies are born at the estimated time of delivery. The date actually gives an indication of approximately when you can expect the baby to be ready to face the world. The date on which you expect to give birth can also be changed a few days earlier or later when you have an ultrasound scan, as this allows the medical staff to measure the fetus and thus determine the week of pregnancy. Your due date may also be moved depending on whether you have an extra long or short menstrual cycle.
