Are you trying for a baby?

Motherhood offers you the Ovulation Calculator –  little bit of help if you’re trying for a baby. The Calendar helps you to work out your fertile days quickly and easily.

 

A woman is able to conceive only during a certain part of the month – Just before and during ovulation.

 

By learning when you ovulate, you can predict when you’re likely to be fertile. This calculator provides approximate ovulation dates and fertile times for women who have regular periods. (Regular periods mean having a period every 21 to 40 days.)

 

The best time to try and conceive is during the ‘fertile window’ of the menstrual cycle; this is different for different women.

 

Fertile Window:  A woman is able to conceive possibly during the five days before ovulation through to the day of ovulation.These six days are the ‘fertile window’ in a woman’s cycle, and reflect the lifespan of sperm (5 days) and the lifespan of the ovum (24 hours).

 

Ovulation : The process when mature  eggs is released by the ovary & travels down to the fallopian tube where it may be fertilised by the sperm.The process usually occurs between the 10th and 19th day into the menstrual cycle, and this is the time where humans are most fertile.

 

Track Your Ovulation :  Ovulation itself generally occurs between day 10 and day 19 of the menstrual cycle, or 12 to 16 days before the next period is due.

 

Depending on your cycle length the most fertile days in the cycle varies:

  • If you have 28 days between periods ovulation typically happens on day 14, and the most fertile days are days 12, 13, and 14.
  • If you have longer cycles, say 35 days between periods, ovulation happens on day 21 and the most fertile days are days 19, 20, and 21.
  • If you have shorter cycles, say 21 days between periods, ovulation happens on day 7 and the most fertile days are days 5, 6, and 7.

 

Detecting Ovulation : Signs and symptoms of ovulation will vary for every woman, but for some, physical indicators can help pinpoint ovulation and help keep track of future ovulation.

 

  1. Hormonal changes in your body
  2. A one-sided backache, or a tenderness in your tummy which  may last a few minutes to a few hours
  3. Cervical Mucus : Around the time of ovulation, you may notice your vagina’s mucus is clear, slick and slippery, the consistency of egg white. This is the best sign of when ovulation is actually happening. It’s prime time for action
  4. Record your basal body temperature (BBT) each day before getting out of bed. A special basal body temperature thermometer will ensure accurate measurement. Your BBT rises about half a degree Celsius after ovulation has occurred. By charting your temperature, it’s easy to see when the rise in temperature and ovulation happens.
  5. Use the Motherhood Ovulation calculator  if you know the date of your last period, the length of your cycle and your cycle is regular, this will identify your ‘fertile window’ and predicted ovulation date.

 

Ovulation Myths

 

Myth 1: “ The best time to try to conceive is day 14 of your menstrual cycle.”

Fact :The only time a woman can conceive is during the ‘fertile window’ of the menstrual cycle.

 

Myth 2 : “A normal menstrual cycle is 28 days.”

Fact :  Actually, a normal menstrual cycle can vary from about 24-36 days. And not only do cycles vary substantially among women, they often vary within each individual woman.

 

Myth 3 : “Sperm can only live up to three day”

Fact : Sperm can survive up to five days in the woman’s reproductive tract.
