1. Differences in menstrual flow

Every woman's menstrual flow is different, some women have a larger flow, and some have a smaller flow. Therefore, menstrual flow is one of the main factors affecting how many sanitary napkins you need to use in a day.

Women with heavy flow: In the early stage of menstruation (especially the first two days of menstruation), many women have heavy flow. At this time, the absorption capacity of sanitary napkins may be used up quickly and need to be changed frequently. People with heavy flow may need to use 4 to 6 sanitary napkins a day, or even more. For women with particularly heavy flow, you can choose super absorbent or night-use sanitary napkins, which have stronger absorption capacity and are suitable for long-term wear.

Women with medium flow: Most women have a medium flow. Such women may use 3 to 4 sanitary napkins a day. Depending on the specific flow, ordinary sanitary napkins are used during the day, and night-use sanitary napkins can be selected at night to ensure that there is no leakage during sleep.

Women with less flow: Women with less menstrual flow may only need to use 2 to 3 sanitary napkins a day, and even one sanitary napkin is enough in the later stages of the menstrual period. For women with less flow, ordinary sanitary napkins with less absorption can be selected.

2. Absorption capacity of sanitary napkins

Different brands and types of sanitary napkins have different absorption capacities. Some sanitary napkins are suitable for daily use, while others are suitable for long-term use at night. When choosing sanitary napkins, absorption capacity is a very important reference standard.

Ordinary sanitary napkins: Suitable for women with less or medium flow, and better effect during daytime use. Usually need to be changed every 4-6 hours.

Super absorbent sanitary napkins: Suitable for women with heavy flow, especially in the first two days of heavy menstrual flow. They have strong absorption capacity and are suitable for long-term use during the day or at night.

Night-use sanitary napkins: These sanitary napkins are designed to be larger and absorb more, suitable for use during sleep, to avoid leakage at night due to long-term non-change.

Sanitary pads: Suitable for women at the end of menstruation or with less flow. They can be used to keep dry and avoid dirtying underwear.

3. Different stages of the menstrual cycle

During different stages of menstruation, the flow also changes, so the number of sanitary napkins used will also be different.

Day 1-2 of menstruation (heavy flow): Most women have a heavy flow in the first two days of menstruation. At this time, you may need to change sanitary napkins frequently, and you may need 4 to 6 pieces a day. Women with heavy flow can choose night-use or super-absorbent sanitary napkins with strong absorption to ensure no leakage.

Day 3-4 of menstruation (medium flow): In the middle of menstruation, the flow begins to decrease, and the frequency of changing sanitary napkins will also decrease slightly. At this time, you may only need 3 to 4 sanitary napkins a day, and you can choose ordinary sanitary napkins that suit your flow.

Day 5-7 of menstruation (less flow): Entering the late stage of menstruation, the flow decreases, and the frequency of using sanitary napkins will also decrease. At this time, women with less flow may only need 2-3 sanitary napkins a day, and can choose ordinary or thin sanitary napkins.

4. Personal lifestyle and habits

In addition to flow and the absorbency of sanitary napkins, your lifestyle and personal habits will also affect how many sanitary napkins you use in a day.

Frequently active women: If you have a lot of activities in a day (such as sports, going out, etc.), you may need to change sanitary napkins more frequently to keep dry and comfortable and avoid leakage.

Sitting for a long time while working or studying: If you are stationary most of the time (such as working at a desk, attending classes, etc.), you may feel that the flow on the sanitary napkin accumulates quickly, and you also need to change it in time.

Needs during sleep: When sleeping at night, since sanitary napkins are not changed for a long time, it is recommended to choose night-time sanitary napkins with strong absorbency to ensure that there will be no leakage problems.
