Find Your Most Fertile Days Now →The 28-Day Cycle: A Typical Timeline
A 28-day cycle is often considered the "average", but it's important to remember that cycle lengths can vary. Here's how a typical 28-day cycle breaks down:
- Days 1-5: Menstruation (period). This is when you shed the uterine lining.
- Days 6-13: The follicular phase. Your body prepares to release an egg. Estrogen levels rise, thickening the uterine lining.
- Day 14: Ovulation. The ovary releases a mature egg.
- Days 15-28: The luteal phase. Progesterone levels rise to prepare the uterus for a potential pregnancy. If fertilization doesn't occur, hormone levels drop, leading to menstruation.
Pinpointing Ovulation in a 28-Day Cycle
Generally, women with a 28-day cycle ovulate around Day 14, give or take a day or two. However, several factors can influence the precise timing of ovulation, making it crucial to understand your body's signals.
- Basal Body Temperature (BBT): Your BBT rises slightly (about 0.5 to 1 degree Fahrenheit) after ovulation. Tracking your BBT can help you identify when you ovulate.
- Cervical Mucus Changes: As you approach ovulation, your cervical mucus becomes clearer, slippery, and stretchy, resembling raw egg white. This is the most fertile type of cervical mucus.
- Ovulation Predictor Kits (OPKs): These kits measure luteinizing hormone (LH) in your urine. A surge in LH indicates that ovulation is likely to occur within 24-36 hours.
Maximize Your Chances of Conception
Sperm can survive in the female reproductive tract for up to five days. To increase your chances of conceiving, have intercourse in the days leading up to ovulation and on the day of ovulation itself.
