Eggs are produced during the menstrual cycle, usually starting on day 14 of a woman's menstrual cycle and reaching peak concentration on day 16. Eggs usually only survive for 1-2 days, so later in the cycle, women need to take steps to ensure that the eggs can be successfully fertilized.

The follicular phase refers to the 13th to 15th day of a woman’s menstrual cycle. During this stage, a woman’s ovaries begin to produce eggs. Eggs are transparent and vary in shape, usually only 1-2 mm in size.

During this stage, a woman's egg is forming and waiting to be expelled into the fallopian tube. If a woman's menstrual cycle is 28 days, the follicular phase usually lasts 10-14 days.

So, what is ovulation?

Ovulation refers to days 14-17 of a woman's menstrual cycle. At this stage, a woman's eggs are mature and ready to be expelled into the fallopian tube. The release of an egg is a critical step in the monthly cycle, and if women fail to fertilize during this period, they need to wait until the next menstrual cycle to try again.

Therefore, it can be said that the follicular phase is the stage before ovulation, and ovulation is the stage when the egg matures and is ready to be released.

So, why is the egg period the ovulation period?

The egg phase and ovulation phase are similar and both refer to specific stages in a woman’s menstrual cycle. During this period, a woman's ovaries begin to produce eggs, which are waiting to be expelled into the fallopian tubes. Therefore, the egg period and ovulation period complement each other and are closely related.

So, if a woman wants to get pregnant, when should she have sex?

Generally speaking, if a woman wants to get pregnant, she should have sex during her ovulation period. This is because during this period, the woman's eggs are mature and ready to be excreted into the fallopian tubes. If the eggs are successfully fertilized, it is possible for the woman to become pregnant again in the next cycle.

Therefore, if you want to get pregnant, you should have sex during a woman's egg stage.
