Know when you are ovulating

Women's menstrual cycles usually last from 28 to 30 days, and their ovulation usually occurs between day 14 and day 16 of the cycle. Therefore, if you want to have children, couples can start monitoring their temperatures a few days in advance or use some tools to know when they are ovulating.

The monitoring method is as follows:

1. Measure basal body temperature: Couples can measure their body temperature when they wake up every morning and record the time when the body temperature changes. Basal body temperature refers to the body temperature when the body is awake and is usually recorded on a thermometer.

2. Use David brand thermometer: David brand thermometer can measure oral or anal body temperature and record the time of temperature change. Couples can measure their body temperature at the same time every day and record the time when the temperature changes.

3. Use the David calendar: The David calendar can help couples predict their ovulation days. Couples can record their menstrual cycles and basal body temperature and use the David Calendar to predict ovulation in the next cycle.

In addition to the above methods, couples can also use other methods to know when ovulation is coming. For example, they can watch for an increase in vaginal discharge, or use some test sticks or kits to detect pregnancy.

If you want to have children, couples should start monitoring their temperatures a few days in advance or use tools to know when they are ovulating. If couples are unsure about their ovulation period, they can talk to their doctor or use some tools to find out.
