Charting your oestrogen readings daily will help you become more familiar with your own ovulation timing. Every woman's body is different, and many of us don't have an exact 28 day ovulation cycle, but if you track your own unique cycle, you can build a personal ovulation calendar. Over time, this will help you predict the best time to fall pregnant each month.

Many women trying to get pregnant use ovulation calendars to help them determine and predict their ovulation date.

And because Maybe Baby is 98% accurate if used correctly, you will be able to pinpoint when you ovulate and the days preceding ovulation with confidence, so you know when you are most likely to become pregnant every cycle.

Please note that anything that is in contact with your saliva besides water in the 3 hours prior to using Maybe Baby may cause an inaccurate reading. This includes but is not limited to toothpaste, chewing gum, cigarettes, mouthwash, food, and drinks except water. You may find it most convenient to use Maybe Baby every morning just after you wake up.
