How to calculate ovulation if menstruation is abnormal?

First, people with irregular menstrual periods should observe their menstrual cycles. A normal cycle should be 28 days, but it may be longer or shorter in some people. Watching your cycle can help determine the best time to get pregnant.

Secondly, people with irregular menstruation can use some measurement tools to calculate ovulation. These tools include thermometers, David pregnancy tests and websites that can measure basal body temperature, serology tests and blood tests to calculate ovulation, among other methods.

Finally, people with irregular menstruation should avoid having sex during ovulation. Because at this time, a woman's uterus may contract, which may cause discomfort and bleeding. Therefore, having sex during ovulation may lead to adverse consequences.
