Are you referring to your menstrual cycle tracker? Or are you using the My Cycles app as well?
According to your menstrual cycle tracker, you are on cycle day 33.
If you are using the My Cycles app, the pink/red lines on certain dates are when you are on your period. The green lines are when you are expected to be fertile or in other words, when you would likely ovulate.
Your predicted period is shown with pink/red and white lines.
Have you entered new information that would change the date of your predicted period? If you enter information about an ovulation test, it could change your expected period date.
However, like momof3gramof2 stated, it is not uncommon to have your cycle vary by a day or two.
Please let us know if we can help in any other way.
Are you concerned that you are pregnant?
There are different numbers of days in months, and it is not uncommon to vary by two days, UNLESS you suspect you are pregnant.
I am not sure what you mean by calendar cycle, red lines and green lines, but it must be some sort of guide...
