It's not a stupid question. My periods have always been irregular too, but the best way i have found to get an idea of when my next one comes i mark a dot next to the date i started on a calender. Mine usually lasts for 3-5 days also. If i start in the 23rd then usually i start again between the 21st and the 23rd. A lot of people don't have the 28 day cycle some people go longer and some not as long so really you need to start marking each time you start so you get an idea of when its due. I hope this helped.

Good morning. You start counting from the 1st day you start bleeding. keep in mind 28 is average, not all women have a 28 day cycle. Some are more and some are less. Once your cycle becomes regular you will be able to determine the amount of days in your cycle.

scythe agony auntheya,

basically, every womens menstruation cycle is different. the average is 28 days in between. i have had my period for around 4 years now, and ever since 3 years ago I have recorded how many days in between periods. mine tend to last for 4-7 days and range from 23 to 40 days in between with the average being around 30 days in between. even now, i can never properly guess the day i get my period, but i have it down to the week i will get it in.

basically, start circling the days you start on a mini-calender and you will be able to roughly estimate when you are going to get your next period. for now, use 28 days as a guide. So be prepared to get your next period near the 14th of feb, or atleast during that week.

hope this helped!
