Contraception for girls during ovulation

First, we need to understand what is ovulation in women. A woman's menstrual cycle usually lasts from 28 to 35 days, and a woman's ovulation period usually occurs between the 14th and 19th day of the menstrual cycle. During this time, the woman's eggs mature and are released. If the woman is fertilized during this time, the fertilized egg will implant and develop in the uterus, resulting in pregnancy.

Therefore, in order to prevent pregnancy, women need to avoid having sex with their husbands during the woman's ovulation period. However, how to calculate a woman's ovulation period and take contraceptive measures is still a difficult problem. Here are some commonly used methods:

1. Measure basal body temperature: Women can determine their ovulation period by measuring basal body temperature. When you wake up every morning, place the thermometer under your tongue for 30 minutes and record the measurement results in a temperature record book. Generally speaking, women's ovulation will occur when the body temperature rises within the range of 0.3 to 0.5 degrees Celsius.

2. Use contraceptive tools: Women can use contraceptive tools to prevent pregnancy, such as oral emergency contraceptive pills, contraceptive rings, contraceptive syringes, etc.

3. External ejaculation: Women can use external ejaculation to prevent pregnancy. This method requires women to expel sperm from the body in advance and leave a clean space in the body for sperm to be fertilized outside the body. However, this method doesn't always work because sperm can survive outside the body for several hours.

4. Avoid using emergency contraceptive pills: Emergency contraceptive pills are an emergency contraceptive method, but they do not prevent pregnancy in the long term. Therefore, women should avoid using emergency contraceptive pills and instead choose other long-term contraceptive methods.

In summary, women need to understand their ovulation periods and take steps to protect themselves. If a woman is unsure of her ovulation period, she can consult a doctor or professional counselor, or use some method of measuring basal body temperature or using contraceptives to determine her ovulation period.
