My menstruation has been irregular, how to calculate ovulation?

First, we need to understand what a menstrual cycle is. The menstrual cycle refers to the duration of a woman's menstruation, usually a 28-day cycle, but some may fluctuate to 30 days or longer. If women have irregular menstrual cycles, the length of their menstrual cycles may affect when they ovulate.

Next, let’s calculate ovulation. For women with irregular periods, here are some ways to calculate ovulation:

1. Basal body temperature method: Measuring basal body temperature can help women calculate their ovulation period. When you wake up every morning, take your oral temperature (oral surface measurement) and record it. If the body temperature rises by 0.5 to 1 degree, then this day is the woman's ovulation period. This method requires consistent measurements to make accurate calculations.

2. Calendar method: Record a woman’s menstrual cycle on a calendar and calculate ovulation based on the date. This method requires women to record their menstrual cycles and requires a certain amount of patience and perseverance.

3. Thermometry: Measuring oral or anal body temperature can help women calculate ovulation. To measure, place the thermometer under your tongue and record the temperature change. If the body temperature rises by 0.5 to 1 degree, then this day is the woman's ovulation period.

The above are some ways to calculate ovulation, but these methods are not always accurate. For women with irregular menstruation, it is recommended to consult a doctor or professional nutritionist for a more accurate method of calculating ovulation.

Finally, I would like to remind women that even if they have irregular menstrual cycles, they can still predict their ovulation with these methods. If women have shorter menstrual cycles, their ovulation may be earlier or later, so women need to be patient and wait.
