To track your menstrual cycle, identify your expected window of ovulation and follow the steps such as –
Step 1 – Plan on tracking your menstrual period for 8 to 12 months.
Step 2 – Day 1 will be the first day to start your menstruation.
Step 3 – Pick the longest and shortest of cycles for your monthly tracking.
Once you know your average menstrual cycle length, you can work out when you ovulate. Usually, ovulation happens about 14 days before your period starts. So, for a usual 28 days cycle, the most fertile window is between day 10 to day 18 of cycle.
