How to calculate ovulation when menstruation is delayed?

First, we need to understand what menstruation is. Menstrual period refers to the time when a woman bleeds every month, which usually starts on the first day and lasts for about 2-8 days.

Then, we need to understand what ovulation is. Ovulation refers to the time period when an egg is released from a woman's body, usually around 14 days after her period.

Next, we can use the following methods to calculate ovulation:

1. Basal body temperature method: measure your body temperature every morning when you wake up. If your body temperature starts to rise around 14 days after your period, that may mean you're about to ovulate.

2. Calendar method: Divide the menstrual cycle into 12 phases, each phase lasting 4 days. In the last few days of the third phase, the day you calculate is ovulation.

3. David's test strip method: David's test strip is a pregnancy test strip. It can usually detect pregnancy about 14 days after menstruation.

None of the above methods are absolutely accurate, so if you're not sure whether you're ovulating, it's best to consult your doctor or a professional fertility consultant.

How to calculate ovulation when menstruation is delayed? While there are ways to calculate ovulation, it's best to get help from a doctor or fertility counselor to determine the exact day. At the same time, if you are considering pregnancy, it is best to take steps to avoid becoming pregnant.
