The ovulation period on the 18th is a very important day, because at this time, the female egg begins to be discharged from the ovary and can meet the sperm to complete the process of fertilization and fertility.

For couples who want to have children, the ovulation period on the 18th is a day not to be missed. This day can be predicted and calculated by:

1. Measure basal body temperature: Women can measure their body temperature when they wake up every morning and record it in a table. If the body temperature exceeds 37 degrees on the 18th, then this day is the woman’s ovulation period on the 18th.

2. Observe the menstrual cycle: If a woman’s menstrual cycle is 30 days, you can observe her menstrual cycle. If the 14th day of the cycle falls on the 18th, then this day is the woman’s ovulation period on the 18th.

3. Use a pregnancy test stick: If the above methods cannot accurately predict the ovulation period on the 18th, you can use a pregnancy test stick to test whether fertilization has occurred.

Ovulation on the 18th is a very important day, and couples who want to have children should plan and prepare carefully. If you are pregnant, don't forget to maintain healthy eating habits and appropriate exercise to help the healthy development of the fetus.
