Ovulation should be from the 29th of last month to the 8th of this month when you get your period on the 18th. If you have your period on the 18th, then about the 4th would be the day of ovulation. The 5 days before and 4 days after the day of ovulation, together with the day of ovulation, totaling 10 days, are called the period of ovulation. For women who have regular periods, the day of ovulation is usually about 14 days before the next menstrual period, and the 5 days before and 4 days after the day of ovulation, together with the day of ovulation, totaling 10 days, are called the period of ovulation. So if you have your period on the 18th, then the 10 days from the 29th of last month to the 8th of this month is the ovulation period. By having sex during this period, a woman’s chances of conception are higher. Generally during ovulation, some women will also experience symptoms such as decreased appetite, high energy and high sex drive. At the same time, a woman’s vaginal mucus will become thin. A few women will also experience a small amount of vaginal bleeding or ovulation pain. If there is any discomfort, it is recommended to consult a doctor promptly.
