Introduction

In general, intercourse can occur on the day before ovulation and on the day of ovulation itself. The ovulation period is when a woman has a higher chance of becoming pregnant. For women with regular menstrual cycles, ovulation typically occurs around 14 days before the start of the next menstrual period. The period including the five days before ovulation, the four days after, and the day of ovulation itself—spanning approximately 10 days—is referred to as the ovulation period.

Generally, to increase the chances of conception, it is recommended to have intercourse every two days or every other day starting from the first day of the ovulation period, continuing until the end of the ovulation period. A detailed explanation is as follows:

The ovulation period is the time when a woman's chances of conception are higher. For women with regular menstrual cycles, ovulation typically occurs around 14 days before the next menstrual period begins. The period including the five days before ovulation, the day of ovulation, and the four days following it—making a total of ten days—is referred to as the ovulation period. Having intercourse at an appropriate time during this period can increase the likelihood of conception. During the ovulation period, it is recommended to maintain intercourse every two days or every other day, starting from the first day of the ovulation period until its end. This frequency can ensure sperm quality while also increasing the chances of conception.

During the preconception period, both partners should maintain good lifestyle habits, including regular sleep patterns, balanced nutrition, and appropriate exercise, all of which can help improve fertility.

Is the chance of getting pregnant high if having sex 8 days before menstruation?

If the menstrual cycle is regular (e.g., 28–30 days), ovulation usually occurs approximately 14 days before the next menstrual period. Eight days before menstruation, the ovulation period has typically already passed, and the egg has lost its ability to be fertilized; thus, the likelihood of pregnancy during intercourse at this time is low. However, it should be noted that even with a regular cycle, slight variations may occur due to factors such as emotional state or stress, potentially delaying ovulation and leaving a small chance of unintended pregnancy.

Is it safe if a condom slips off halfway?

If the condom slips off halfway but no ejaculation has occurred, or if it is promptly removed after ejaculation without semen spilling or coming into contact with the vulva or vaginal opening, and if this happens outside the woman's ovulation period (approximately one week before or after menstruation), the risk is likely low. There is no risk of semen entering the vagina, and the probability of conception during non-ovulatory phases is minimal. Simply maintaining proper hygiene afterward is sufficient; there is no need for excessive concern.

Does dry underwear mean menstruation is coming?

If it is the late luteal phase of the menstrual cycle, 1–2 days before the expected onset of menstruation, dry underwear is mostly caused by changes in estrogen and progesterone levels. Before menstruation begins, cervical and vaginal mucosal secretions are significantly reduced compared to the ovulation period, leading to dryness in underwear. This condition aligns with normal physiological changes prior to menstruation. If menstruation starts on time afterward, no special concern is needed.

Does a 14-year-old girl have an ovulation period?

Most 14-year-old girls have already begun ovulating, although their ovulation may not yet be regular. At this stage, girls' reproductive systems are gradually maturing, but there are individual differences in development. Parents should pay attention to their daughters' physical changes and provide proper health guidance to help them understand their own bodies. Girls themselves should also develop good hygiene habits, maintain an optimistic mindset, and smoothly navigate through adolescence.
