Ovulation and Fertility - What You Should Know
Ovulation is an incredible part of the menstrual cycle, marking the release of a mature egg from an ovary. It’s all about timing and balance, with key hormones like luteinising hormone (LH) and follicle-stimulating hormone (FSH) driving the process. For most women, ovulation happens around the midpoint of their cycle, typically 12 to 16 days before their next period. Once released, the egg is ready for fertilisation for only 12 to 24 hours. Sperm, however, can hang around in the reproductive tract for up to five days—creating a fertile window of about six days where conception is possible if the timing is right.
When Does Ovulation Happen?
While ovulation generally happens around day 14 in a textbook 28-day cycle, real life is often less predictable! Each woman’s cycle is unique, and factors like stress, illness, or hormonal changes can shift the timing. Keeping track of your cycle with a calendar or app can help you notice patterns and get a clearer idea of when ovulation might occur. And your body gives you clues too—like changes in cervical mucus (it may become clearer and stretchy) or even mild twinges of abdominal discomfort.
The more you tune into your body and its rhythms, the easier it becomes to understand your fertile window—an empowering step on your fertility journey. The following methods can help you track when ovulation occurs for you:
- Vaginal changes: The vagina produces a clear, jelly-like fluid right before ovulation. This can help you assess your ovulation period.
- Body temperature: During ovulation, your body basal temperature is elevated. A body temperature measurement can also help you determine whether you're ovulating or not.
- Ovulation kit: Use a home ovulation test kit to determine your ovulation date through your urine.
