How to Use a Period Calculator

To use a period calculator, you'll need to know:

1. The first day of your last period.
2. The length of your period.
3. The average length of your cycle.

Example:

• Last period: December 2, 2024
• Period duration: 5 days
• Average cycle: 28 days

Enter this information into a calculator to predict your next period, ovulation window, and fertile days. Remember, this is an estimate, and many factors can affect your cycle's regularity.

Understanding Your Menstrual Cycle

A menstrual cycle has two main phases:

1. Follicular Phase

• Begins on the first day of your period.
• Hormones like estrogen rise, preparing an egg for ovulation.
• Ends with ovulation (around day 14 in a 28-day cycle).

2. Luteal Phase

• Begins after ovulation and lasts until the start of the next period.
• Progesterone rises to prepare the uterus for implantation.

Cycle Length:

• A normal cycle lasts 21 to 35 days.
• Periods usually last 2 to 7 days.

Irregular Cycles:

Factors like stress, PCOS, or weight changes can affect cycle regularity. If your cycle is consistently irregular, speak with a healthcare provider.

Signs Your Period Is Coming

Your body often signals that your period is approaching. Common premenstrual symptoms include:

1. Tender Breasts

• Caused by rising progesterone levels after ovulation.

2. Acne

• Hormonal changes may lead to breakouts before your period.

3. Cramps

• Prostaglandins cause uterine contractions, resulting in menstrual cramps.

4. Mood Swings

• Fluctuations in estrogen and progesterone can affect emotions.

5. Bloating

• Hormonal changes and water retention are common before a period.

6. Fatigue

• Changes in serotonin levels may cause tiredness.

7. Changes in Vaginal Discharge

• Discharge may become sticky or dry before a period.

Why Is My Period Late?

A late period can be caused by:

• Pregnancy: Take a test if you’ve had unprotected sex.
• Stress: Cortisol can delay ovulation and your period.
• Weight Changes: Significant weight gain or loss can impact your cycle.
• Health Conditions: PCOS, thyroid issues, or perimenopause may cause irregular periods.

If your periods are consistently late or irregular, consult a healthcare provider.
