Ovulation and safety periods are critical times for maintaining fertility, but many people don’t know which day they are. Next, we will introduce how to determine these times from the perspective of ovulation and safety periods.

So, what is the follicular phase? The follicular phase refers to the period between days 11 and 19 of the menstrual cycle, which is the stage when a woman’s eggs mature and are released. At this time, the woman's ovaries begin to form eggs and gradually mature.

Next, let's look at how the safety period is determined. The safe period is between days 7 and 13 of the menstrual cycle, but this method is not always accurate. Because a woman’s menstrual cycle is affected by many factors, including diet, medications, and lifestyle.

Therefore, the best way is to observe changes in women's body temperature and appetite to determine the safe period. Generally speaking, a woman's body temperature will increase early in the cycle and decrease later in the cycle.
