I have my period in my 20s, when is ovulation?

First, let's calculate your period. If your menstrual cycle is 28 days, the first day of your next period is January 20th. From January 20th to February 17th, is your 12-day cycle. Therefore, your next cycle is February 24th.

Next, let’s look at how to calculate your ovulation date. During a woman's menstrual cycle, an egg is released from the ovary and then enters the fallopian tube to wait for fertilization. Normally, it takes 12-24 hours for an egg to mature. So, if your menstrual cycle is 28 days, your eggs will mature around February 18th.

So, is February 18th your ovulation period? The answer is no. Because February 18th is not a fixed date in your menstrual cycle. Therefore, you need to calculate your ovulation based on your menstrual cycle.

If your menstrual cycle is 28 days, then ovulation takes about 14 days from the first day of your next period. If your cycle is 40 days, then ovulation takes approximately 28 days from the first day of your next period.

To summarize, it is important to know when you are ovulating. If your menstrual cycle is irregular, you may need to rely on a period chart to know when you are ovulating. If you're not sure, talk to your doctor or professional fertility counselor.
