Temperature changes during the first three days of menstruation

Many women use ovulation test strips and pregnancy test strips to help them conceive, but some women think that preparing for pregnancy is more effective through temperature monitoring. How can you know whether you are pregnant by observing the changes in body temperature three days before menstruation? A woman's body temperature will rise during ovulation. This increase is not obvious and needs to be monitored to be known. If the body temperature does not show a downward trend before menstruation, you may be pregnant.

1. What is the reason for a body temperature of 36.3 three days before menstruation?

1. A body temperature of 37.3 three days before menstruation is normal. It should be compared with the basal body temperature during the cycle. A single body temperature is normal. It will only decrease when menstruation is about to come, about one or two days before or after.

2. It is normal for the body temperature to be around 37 degrees during menstruation. During a day and night, the human body temperature fluctuates periodically. The body temperature is lowest between 2 and 6 in the morning and highest between 1 and 6 in the afternoon. The amplitude of the fluctuation generally does not exceed 1°C. This diurnal periodic fluctuation of body temperature is called circadian rhythm or daily cycle.

3. Women's basal body temperature changes with the menstrual cycle. The body temperature rises after ovulation, and this rise continues until the next menstruation. This phenomenon is likely related to the secretion of sex hormones. Experiments have shown that this variability is consistent with the changes in progesterone and its metabolites in the blood.

2. What are the precautions during menstruation?

1. Do not have sex

During menstruation, the cervix is ​​slightly open. Sexual intercourse during menstruation can easily bring bacteria from the vulva and perineum into the vagina, cervix, and even into the uterus, causing endometritis or acute adnexitis (including the fallopian tubes and ovaries) and pelvic peritonitis. In addition, sexual intercourse during menstruation may also cause the shed endometrium to flow back into the pelvic cavity and cause endometriosis. The above symptoms may cause increased menstrual bleeding, prolonged menstrual period, dysmenorrhea and other consequences.

2. Avoid strenuous exercise

It is not absolutely forbidden to exercise during menstruation, but strenuous exercise such as high jumping and running should be avoided as much as possible, otherwise it will aggravate the discomfort during menstruation, such as back pain, and even cause dysmenorrhea and menstrual disorders. Swimming during menstruation should be avoided because the cervix is ​​slightly open during menstruation, making it easy for bacteria to invade the uterine cavity, increasing the chance of infection and causing various gynecological inflammations. Therefore, do not swim during menstruation.

3. Avoid eating raw, cold or overly salty food

Eating raw or cold food or drinking cold drinks during menstruation will affect the contraction of the uterus, causing poor menstrual blood discharge and leading to problems such as dysmenorrhea. In addition, during menstruation, many women tend to become irritable and anxious due to the imbalance of estrogen and progesterone, water and sodium retention, and excessive antidiuretic hormone. Eating too much salty food will aggravate water and sodium retention, leading to problems such as headaches and edema.

You need to pay attention to your diet and lifestyle habits during menstruation. It is best not to stay up late or eat irritating foods during menstruation. Regulating your body in this way can reduce the occurrence of many diseases, especially for women, it can reduce a lot of unnecessary troubles. Women should pay attention to problems during their menstrual period in their daily lives, but it is best to see a doctor during menstruation.
