Ovulation occurs when an egg is released from the ovary and passes into the fallopian tube waiting to be fertilised. Fertilisation by the sperm must occur within 24 hours of the release of the egg. Immediately before ovulation, the woman’s body produces a large amount of a hormone called Luteinizing Hormone (LH) which triggers the release of a ripened egg from the ovary. This is known as the “LH surge”. It is during this fertile time that pregnancy is most likely to occur. It is important to remember that an LH surge and ovulation may not occur in every cycle. For some women, physical indications of ovulation can include: - a slight pain in the lower abdomen;
- their vaginal discharge may increase;
- there may be a slight increase in body temperature
