Period Cycle Calculator

Do you wonder each month 'when is my period due?' Using a period cycle calculator, like our TAMPAX period calculator, can give you a heads up so you’re never surprised when that time of the month rolls around. You’ll know the exact time to expect it. When you track your cycle with a period due calculator and know when to have a tampon on hand, you can face every day with that much more confidence.

First of all, forget any idea of normal. Every girl is different. What’s important is that you find out what’s normal for you; a period due calculator will help you do that. All cycles are unique, but between pre-period, period and ovulation, there are a few things we all have in common:

The dreaded Premenstrual Syndrome. Some common symptoms of PMS are headaches, bloating, irritability and crying more than normal. In other words, that urge to sit on the couch in sweatpants with a tub of ice cream and sob while watching ‘The Notebook’. Yeah, we’ve all been there.

Do you have the 'when is my period due' feeling? It’s common to experience PMS in the 3 days leading up to your period. And just so you know: diet, caffeine and stress can increase the intensity of PMS symptoms.

While these symptoms can be painful and uncomfortable, the good news is there are ways to help manage them:

• Resist the urge to have an extra cup of coffee
• Take an over-the-counter pain killer
• Use a hot water bottle

Period

This is the start of your cycle and when bleeding begins. But why do we bleed in the first place? Since your egg wasn’t fertilised, your womb lining sheds and leaves your body. Thus, blood.

Here are some facts about periods:

• Healthy periods generally last between 4 and 7 days, with the heaviest days being the first and second
• An average cycle is 28 days, but can range from 21 to 35 days (to work yours out use a period cycle calculator)
• Bleeding is usually between 10-80 grams, or 1 to 6 tablespoons of fluid (not that we’re putting a measuring cup down there, but good for keeping track of tampon changes)

See your doctor if you find yourself bleeding through six or seven regular tampons a day or if you have your period for more than 7 days.

This is the time when you’re ovulating and at the highest risk for pregnancy. This fertile time lasts about 6 days. In a 28-day cycle, ovulation typically occurs on day 14.
