An egg is a female's reproductive cell, produced one per month by one ovary. The egg must mature before it can be released from the ovary. The egg matures in a fluid-filled vesicle, and the image of a jellyfish is very appropriate to describe the egg. A woman releases about 400 eggs in her lifetime, and at most 500 eggs. The average survival time of an egg is 12 to 24 hours. There are also reports that an egg can survive for 36 hours, which should be a relatively "strong" egg. The diameter of a mature egg can be 1 mm. As the largest cell in the human body, the egg plays a role in human reproduction.

How many days after menstruation should I test for ovulation?

Female ovulation is affected by endocrine hormones from the pituitary gland and ovaries and changes periodically. The length of the cycles of the two is the same, with one cycle per month, and ovulation occurs between two menstrual periods. Women's menstrual cycles vary in length, but the interval between ovulation and the start of the next menstruation is relatively fixed, usually around 14 days. Based on the relationship between ovulation and menstruation, the ovulation period can be calculated according to the menstrual cycle.

The calculation method is to count from the first day of the next menstrual period, and count down 14 days or subtract 14 days to get the ovulation day. The ovulation day and the 5 days before and 4 days after the ovulation day are called the ovulation period. This is also the theoretical basis of the safe period contraceptive method, because in the menstrual cycle, except for the menstrual period and ovulation period, the rest of the time is the safe period.

For example, if the menstrual cycle is 30 days, the first day of this menstruation is September 29, then the next menstruation will be on October 29 (September 29 plus 30 days), and then subtract 14 days from October 29, then October 15 is the ovulation day. The ovulation day and the 5 days before and 4 days after, that is, the ten days from October 10th to 19th are the ovulation period.

To calculate the ovulation period using this method, you must first know the length of your menstrual cycle, that is, you must have a very normal or regular menstrual cycle, in order to calculate the start date of the next menstrual period and then the ovulation period. Therefore, this method is only applicable to women with normal menstrual cycles. If the menstrual cycle is irregular or abnormal, it is impossible to calculate the date of the next menstrual period, so it is impossible to calculate the ovulation day and ovulation period.

For irregular menstruation, the ovulation period calculation formula is:

Ovulation period: The first day of ovulation = the number of days in the shortest menstrual cycle minus 18 days;

The last day of ovulation = the longest menstrual cycle minus 11 days.

For example, the shortest menstrual period is 28 days and the longest is 37 days. The shortest regular period is subtracted by 18 (28-18=10) and the longest regular period is subtracted by 11 (37-11=26). Therefore, the ovulation period is from the 10th day to the 26th day after the menstrual period.

The above is the introduction about how to test ovulation a few days after menstruation. I believe that after reading the above introduction, you already know how many days after menstruation to test for ovulation. In fact, as long as you know when your ovulation period is, you can start testing from the first day of ovulation! I hope that the introduction in this article will be helpful to those who want to know how many days after menstruation to test ovulation.
