Tiny eggs develop in sacs called follicles in your ovaries.

At any given time, there are follicles at several stages of development in your ovaries Follicles undergo incredible changes leading up to ovulation, developing many parts and layers, each with their own functions. Most follicles, though, will never reach ovulation, dying off at different phases of development or pre-development. By about midway through the follicular phase, one follicle becomes dominant.

Just like a superstar athlete being selected from the pack, all resources then go to preparing that single follicle, and the other potentials die off. When the follicle is ready, it releases its egg. After its release, the egg has about 12—24 hours to be fertilized by sperm in the fallopian tube. If it is fertilized, it travels to the uterus over the following 6—12 days, to possibly implant for pregnancy 12, All of these events are driven forward by the cyclical changes in your reproductive hormones.

Hormones control the selection and development of your follicles, the release of each egg, and the preparation of your uterus for possible implantation. This first part of the cycle is called the follicular phase now you know where it gets its name. The brain produces continuous bursts of follicle stimulating hormone , or FSH, throughout your cycle.

Try to take your temperature at the same time every day, if possible. Create a chart and write down your temperature every day.

If you look at a complete cycle, you will probably notice a point at which the temperatures become higher than in the first part of your cycle. The rise is about 0. Temperature is a useful indicator of fertility. After checking for several cycles, you may be able to see a pattern and identify your most fertile days. Catherino WH.
