Understanding Your Menstrual Cycle Phases

Period Days

These are the days of your menstrual flow, typically lasting 3-7 days. During this time:

  • The uterine lining is shed
  • You may experience menstrual cramps
  • Flow is usually heaviest in the first 2-3 days
  • This marks the beginning of your menstrual cycle

Fertile Window

This is when you're most likely to conceive. It typically occurs:

  • Around 12-16 days before your next period
  • Includes 5 days before ovulation
  • The day of ovulation
  • And 1-2 days after ovulation
  • You may notice changes in cervical mucus

Note: This window can vary significantly, especially with irregular cycles.

Safe Days

These are typically the days when conception is less likely. However, please note:

  • No days are 100% safe from pregnancy
  • Usually includes days after ovulation until next period
  • And a few days after your period ends
  • Varies greatly between individuals

Important: For birth control purposes, please consult with a healthcare provider.
