Can I have sex on the fourth day of my period?

When a woman has her period, her body loses a lot of blood, so she is prone to anemia. In order to solve this problem, women should eat more foods that replenish qi and blood during their menstrual period. First of all, they should eat more foods rich in vitamins, such as vegetables such as cucumbers and tomatoes. In addition, they can eat more red meat, which has a good blood-replenishing effect. In addition, they should pay attention to relevant matters during their period. So, can they have sex on the fourth day of their period?

Can I have sex on the fourth day of my period?

Some people simply summarize the safe period for women as the first three days and the last four days, while others say the first seven and the last eight days, but these are not accurate. In fact, it should vary from person to person. Usually a woman's ovulation day is 14 days before menstruation. Taking into account factors such as the survival time of sperm in the female body and errors, the period between 5 days before and 4 days after ovulation is generally called the "dangerous period". The possibility of pregnancy during this period is relatively high. The other time becomes the "safe period" and it is relatively difficult to get pregnant. In addition, it is obvious that the "safe period" after the "dangerous period" has a higher safety factor.

The safe period algorithm also has certain limitations. For example, some women have irregular menstruation and are not suitable for using the safe period for contraception. In addition, women may also have irregular ovulation due to emotional changes.

The principle of the safe period seems to be quite reliable, but in fact the so-called ideal state does not exist, so it is very difficult to calculate.

The safe period calculation method that you often hear is a simple estimate like seven before and eight after, or three before and four after, but it is only calculated based on the most recent menstrual cycle. For such an algorithm to be accurate, women's menstrual cycles must always be as punctual as a clock. In fact, not all women ovulate regularly. Even for women who ovulate regularly, their menstrual cycles will fluctuate due to the environment, emotions, and health conditions, making it difficult to ensure that they are completely on time. Therefore, such calculations will lead to large errors.

1. Since the time of female ovulation is affected by factors such as the external environment, climate, one's own emotions, health status and physical condition, ovulation may be delayed or advanced, and extra ovulation may also occur, that is, ovulation twice in a month. This is one of the reasons for the high failure rate.

2. Since hormones in the body can also induce ovulation, when two people have sex, if they are particularly excited, it will increase hormone secretion, which may lead to ovulation. Therefore, this is also one of the important reasons leading to high failure rate. Safe period sexual intercourse is suitable for people with normal menstrual cycles, couples who often live together, and who can master and strictly abide by the safe period. Couples who do not live together often, women who have given birth or miscarriage, women who have changes in their mental state, living environment and health, and women who cannot master the safe period, and newlyweds who are emotionally excited and have strong sexual desire are not suitable for safe contraception.
