**cycle**. Then divide this number by the numberof

**cycles**(aka the number of times you've had

**your**period) since counting. This will give you the

**average**number of days between each period, or

**youraverage cycle**length.

Similarly, how do I figure out my average cycle length?

The answer is the date of the first day of yourlastperiod (not the day it ended). Ex.= February 2nd. To**figureout** how long your **cycle** is, start at**cycle** day 1of your last menstrual **cycle** and begincounting(**Cycle** day 1,2,3,4 and so forth). The **length**=thelast **cycle** day before you startedbleedingagain.

**next period**when adding 30 days tothelast. So, if my last

**period**started on February 2, I add30days and come up with March 4 for the first day of my

**nextperiod**.

Also question is, how do I calculate my 28 day cycle?

Your **menstrual cycle** is the time from thefirstday of one **period** to the first day of yournext**period**. So if you have a **28**-day **cycle**,ittakes **28 days** to get from the beginning of one**period**to the beginning of the next.

**The** length of **your** menstrual cycleis**the** number of days from **the** first day of bleedingin**your** last period, to **the** first day of bleedingin**your** next. From this **figure**, subtract 14 daysfrom**the** end of **your** current cycle to **determinethe**approximate day you **ovulate**.
