An egg matures in an ovary, is released into a fallopian tube and finally travels to the uterus (womb). Hormone levels rise and help prepare the uterine lining for pregnancy. If the egg is not fertilised, and the woman is not pregnant, then the lining is not needed and is shed. It is this shedding of the uterine lining that is called your period.What is the menstrual cycle?
A normal menstrual cycle has four phases:
When can I get pregnant?
- The egg ripens
- Uterus implanting a fertilised egg
- If stage 3 doesn’t happen, the uterine lining and unfertilised egg are shed – the period
The most fertile time of the cycle is during ovulation. If you have regular 28-day cycles, ovulation usually occurs on day 14. However, women have different cycle lengths. In general, ovulation occurs 11 to 16 days before your upcoming period.Can I keep track of my period?
