Using an Ovulation Calculator
How can I tell if I’ve ovulated?
Each month an egg is supported towards maturity by the action of hormones on the ovarian follicle in which it rests. Generally a new egg ruptures and is released mid-cycle; around day 14-15 after the first day of the last normal period. If the egg is fertilised and implants in the uterus, there will be no period. If fertilisation does not occur, then the uterine lining and egg are shed in the next period, around 14 days later
How can I tell my most fertile days?
The most common and easiest method of detecting ovulation is to use a monthly calendar. Mark the first day of your menstrual period and when bleeding stops. Doing this for a couple of months will help you to understand your own patterns and the cyclic, generally predictable nature of menstruation.
Although the average length of a menstrual cycle is 28 days, this can vary between individual women. Many women have shorter or longer cycles.
It is important to look for physical changes which can show you’ve ovulated, or are about to. Predicting your most fertile days will help to increase your chances of conceiving
When Should We Try?
Having intercourse just prior to, or at the time of ovulation will maximise your chances of conceiving a baby.
There is only a small fertility window – twelve to twenty four hours, where the egg is viable and capable of fertilisation. Taking your basal body temperature first thing in the morning can also give you some clues as to your most fertile days..
Many women also experience ovulation symptoms such as changes in their vaginal mucous and an increase in their libido.
Sperm are much more robust than eggs and can survive for up to five days after ejaculation. Fertilisation normally occurs in one of the fallopian tubes. As soon as the egg has been fertilised, a signal is given off to the other sperm not to waste their efforts, there has already been a lucky winner.
