How Does My Menstrual Cycle Work?
Your menstrual cycle quite simply determines when you can conceive. This window of opportunity (fertility window) comes around once a month for several days at any given time. This process leads to ovulation and at ovulation your body releases a mature egg and the journey to fertilisation begins.
How Do I Get Pregnant?
If you want to conceive, two processes have to take place:
- Ovulation: Your ovary releases a mature egg mid cycle, this falls due on and around day 15 of a 28-day menstrual cycle. (The day is counted from the day your period begins). Try our Ovulation Calculator for instant results.
- Fertilisation: Once your egg has been released, there is a 12-48 hour period after it’s release when the sperm can successfully fertilise the egg. This is when you are at your most fertile.
When Am I Fertile?
Most women experience a ‘hotspot’ mid cycle this is when you are most likely to conceive. Timing does depends on your cycle length which can obviously vary from woman to woman, with a normal cycle anywhere from 23 to 35 days. However if you have a 28 day cycle it works out a little like this:
- Day One: Your menstrual cycle (period) begins, day one.
- Mid Cycle: You will normally ovulate around day 15 of your cycle.
- Hotspot: Conception is more likely to occur if you have sex in the two or three days prior to ovulation and the day following ovulation, these days are normal days 12-16.
