Ladytimer Period and Ovulation Calendar
There are two approaches to getting pregnant: either get on top of the maths to pinpoint your fertile period, or take the "shock and awe" approach and practise baby-making on a daily basis. If you want to take the mathematical approach, then this iPhone app can help.
Fifth download lucky, the app met two important criteria in that it had enough functionality to be useful, yet was easy to use. This contrasted to an earlier download, Fertility Friend, which offered endless stress-inducing options in an ugly, war tank-type interface.
Start by typing in your period cycle and length. If you don't know, the app promises to work it out for you. Next, enter your last period start and finish date, and you're off.
The app displays a calendar showing your expected ovulation date, which is estimated to be 12 to 16 days before your period starts. Your most fertile period is estimated to be the three days preceding ovulation.
Tap the boy/girl baby icon and the calendar changes to show which days are best for making boys, and which for making girls. I am not sure of the science behind this, but it makes the calendar prettier.
So far, the predictions are estimates based around period dates, but a primary fertility sign is the rise in your body temperature, which follows ovulation. Start tracking this using the app to allow it to fine-tune its estimates.
Other options include tracking your mood, physical symptoms, pill usage and the results of an ovulation test (should you take one). You also get to track your sex life, which is discretely indicated on your calendar with a little heart.
The good news is you shouldn't need the app for too long: for couples who are under the age of 35 and have unprotected sex on a regular basis, statistics show that 85 per cent of women will conceive within one year.
