Period symptoms

  • At the beginning of a period, bleeding is heavier, but it becomes lighter towards the end.
  • Abdominal pain appears usually on the first day of bleeding and can radiate to the lower back. Usually, the pain wears off over time.
  • Gastric disorders – some women may suffer from various gastric symptoms, such as diarrhoea, constipation, nausea, and vomiting.
  • Increased eruptions on the face and body (mainly chest) is caused by lower oestrogen levels, which makes skin dry and sensitive.

What causes fertile days to shift?

Remember that the ovulation calculator and observing your body do not guarantee precise calculation of your fertile window. There is a range of factors that may cause ovulation and fertile days to shift, such as:
– strong stress,
– illness in the first cycle phase and antibiotic use,
– heavy physical strain,
– diet and weight loss,
– climate change,
– sleep deprivation,
– general fatigue.
