Pregnancy calculators are the more convenient method of determining a number of pregnancy related issues including:

  • The gestational age
  • Date of conception
  • When you will give birth (what your OBGYN might refer to as the EDD or expected date of delivery).
  • How far along are you in your pregnancy

The most important date you will need to provide is the date of your last menstrual period or LMP. To go by convention, pregnancies are measured in weeks and pregnancy is assumed to have taken place around 2 weeks after her last menstrual period. Pregnancy calculators are normally free- so unlike ultrasounds, you do not need to fork out any money or book any appointments. This is not to undermine the great importance of an ultrasound to any pregnancy woman. These pregnancy calculators can be found online, or even downloaded as applications on IPhones and Android Phones.
