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.
