The Ovulation Calendar - Why and When does Ovulation occur?
The most common questions are why and when does ovulation occur. The process of ovulation is controlled by the brain and via the release of hormones secreted from the pituitary gland. These hormones are called:
- The Luteinizing hormone (LH)
- The Follicle-stimulating hormone (FSH)
Ovulation is triggered by a surge in the amount of the FSH hormone and LH hormone which are released from the pituitary gland. During the luteal, or post-ovulatory, phase the egg will travel through the fallopian tubes toward the uterus. If fertilized by a sperm, it may perform implantation there 6-12 days later.
Your Personalised Ovulation Calendar - Your most fertile times
The above ovulation calendar indicates just an average of days that ovulation could take place - every woman's cycle is different. To create a more accurate view of your most fertile times you must establish a pattern for your personal menstrual cycle. This cannot be done instantly as it is necessary to chart your menstrual cycle for at least 8 months to gain an accurate picture. To identify your most fertile times on your personal ovulation calendar you need to use your longest and shortest cycles.
To establish the first day of your fertility window:
- Take the number of days of your Shortest cycle e.g. 25
- Subtract 18 from this number e.g. 25 - 18 = 7
- The first day of your personalised Ovulation calendar starts on the 7th day of your cycle
To establish the last day of your fertility window:
- Take the number of days of your Longest cycle e.g. 32
- Subtract 11 from this number e.g. 32 - 11 = 21
- The last day of your personalised Ovulation calendar ends on the 21st day of your cycle
Your ovulation can be expected during this period. You cannot get pregnant everyday during this time, but these re the most likely times that pregnancy can occur.
