Taking your cervical temperature

When a woman ovulates (or releases an egg) her temperature rises slightly and stays elevated for at least 10 days. Taking your temperature daily can reveal this pattern to show you when your body tends to do this. As a guide, ovulation usually occurs 14 days before the next period is due to arrive.

Physical signs of ovulation

Each month, women experience ovulation - the phase of the menstrual cycle that involves one of the ovaries releasing an egg (ovum). It generally occurs about two weeks before your period starts. If that ovum meets a sperm on its path along the fallopian tube, your journey to motherhood has begun.

Rhesus disease

Rhesus disease can occur in pregnancy when there’s a Rhesus incompatibility between mother and baby. The condition is unusual but serious when it occurs.

Ectopic pregnancies

An ectopic pregnancy occurs when a fertilised egg implants inside the fallopian tube instead of the uterus. It is a non viable pregnancy and an extremely serious condition that needs urgent attention.

Ovulation phase of menstrual cycle

When a woman ovulates, she releases a mature egg from one ovary (or two eggs if she is having twins). The egg is released into the adjacent fallopian tube and can survive in the woman's body for around 12 to 24 hours. Sperm needs to reach the egg before this time lapses.
