Pregnant, or just thinking about it? Looking for some high-quality resources you can trust – we’ve taken the hard work out of it for you here with a range of the best due date, ovulation and BMI calculators and a selection of week-by-week pregnancy trackers.

Due Date Calculators

Pregnant and curious about what your baby’s date of birth will be? A due date calculator will give you an estimated date. The estimate is nothing more than a rough idea of when your baby might arrive. Only 3-5% of babies are born on their due date. Full term pregnancy is anywhere between 37 and 42 weeks of pregnancy.

Pregnancy, Birth and Baby is a national helpline, video and website service that supports expecting parents and parents, families and carers of children aged up to five years. Healthdirect Australia delivers the service on behalf of the Australian Government. 

You can also estimate your due date.

YourDueDate.com is a bespoke calculator that includes:

  • Estimated Due date
  • Conception Date
  • Baby Status (Size, Weight, Heartbeat)
  • Due Dates for Multiples (Twins, Triplets, Quads)
  • Trimester Stages
  • Prenatal Testing Dates
  • Timeline of Significant Milestones in Embryo/Fetal Development
  • Imagine, Your Baby Will...
  • Fun Due Date Facts
  • Famous People Born on The Due Day
  • The Due Day In History

You can also calculate more than just the first day of your last period. Other options include:

  • First day of my last period
  • Conception Date
  • (Projected) Due Date
  • Date of Ultrasound
  • IVF Transfer Day
  • Advanced Method 

Follow your pregnancy body and your baby’s development week by week, from the moment of conception to your due date with Elevit’s due date calculator. 

At babycenter.com.au use the due date calculator to see major milestones and sign up to receive free weekly newsletters tracking your baby’s development and yours throughout your pregnancy. 

Check your IVF or FET due date at Your IVF Journey. It works if you’ve had donor eggs, donor embryos or a frozen embryo transfer (FET).

Ovulation Calculators

The babymed.com ovulation and fertility calendar helps predict when you ovulate, your fertile days for sexual intercourse and also shows you when to expect the first pregnancy signs and symptoms.

The webmd.com ovulation calendar shows the fertile window, approximate ovulation, next period and pregnancy test day. 

BMI Calculators

It’s important to eat well when you’re pregnant to give your baby a healthy start, but you don’t have to eat for two. While most women gain between 11.5kg and 16kg, how much weight you gain is influenced by:

  • Your weight before you were pregnant. You may need to gain a little more if you were underweight, or if you’re overweight you should gain a little less.
  • Whether you’re carrying twins or higher order multiples.
  • The impact of morning sickness.

For a week-by-week recommendation on weight gain and recommended weight range for delivery, the bespoke pregnancy weight gain calculator at calculator.net offers detailed insight.

Below is a selection of websites that present the week-by-week breakdown of pregnancy in motion.
