The Duke and Duchess of Sussex said their first child should arrive in late April or early May. The full moon that begins on Good Friday is known as the Pink Moon and hopes to encourage the arrival of Meghan's baby. Evidence suggests that labor can be induced from the lunar cycle and from the beginning of the full moon. According to evidence, the gravitational force of the full moon can affect the amniotic fluid that surrounds the baby.
The impact is similar to how it affects the sea and rivers, and influences levels of the hormone melatonin, which regulates sleep cycles.
The maternity wards are also supposedly busier during the full moon.
However, there is debate in the medical industry whether the moon really encourages women to go into labor.
Kate, the Duchess of Cambridge, was born with her first Prince George on the full moon on July 22, 2013.

She also went into labor with Princess Charlotte two days before the full moon.
Although, when she gave birth to Prince Louis, the moon was only in the first quarter.
The name of the Pink Moon originates in the Native American traditions of time keeping, which were later adopted by colonial Europeans.
Many tribes, particularly in the eastern half of the United States, would call the Full Moons in response to changes in the seasons and the unstable landscape around them.
The color of the moon comes not only from its color but from the flowers that bloom in early spring in the US and Canada which are known as phlox or creeper phlox.
The phlox usually blooms around this time of year, leaving the pink fields around the Appalachian mountain ranges in present-day Pennsylvania and northern Georgia.
If the baby arrives on Easter Sunday, it will be on the same day as the queen's birthday.
