How to calculate ovulation when I haven’t had my period?

Generally speaking, a woman's menstrual cycle is 28 days, but some may fluctuate to 30 or 32 days. If the cycles are not regular, the best calculation method will need to be determined based on history or a doctor's advice.

However, regardless of the length of the cycle, the basic calculation method is to calculate the day when the next menstruation comes, and then calculate the ovulation period of about 10 days from this day. This is because, during ovulation, a woman's eggs may mature and be released, which is an important period for pregnancy.

Here are some ways to calculate ovulation:

1. Basal body temperature method: Measuring basal body temperature can help determine a woman’s ovulation period. Upon waking each morning, take your temperature and record it on a chart. If the body temperature rises by more than 0.5°C, ovulation may be imminent.

2. Calendar method: Record a woman’s menstrual cycle and the day of her last menstrual period on a calendar, and then calculate the ovulation period based on the cycle and the day of her last menstrual period.

3. David's thermometer method: Using a David's thermometer to measure basal body temperature can help determine a woman's ovulation period.

The above method may not be the only calculation method, because everyone's cycle is different, so you need to choose a calculation method that suits you according to your own situation. If you're not sure how to calculate ovulation, talk to your doctor or professional advisor.

How to calculate ovulation when I haven’t had my period? No matter which method of calculation is used, remember that pregnancy is always a possibility if no contraceptive measures are taken. If you have any concerns or concerns, please consult a physician or professional advisor.
