The average period lasts up to 28 days, but it's completely normal to have a slightly longer or shorter cycle. No need to worry as it's all very natural. Considering that, the period calculator is not 100% accurate for girls who have irregular periods, as its extremely complicated to predict the date of the next period in those cases, however, it can help give you an overview of just how irregular your period is and therefore have more of an idea of what to expect in future.

All menstrual cycles are unique, but we do have some things in common:
Pre-Period
Premenstrual Syndrome otherwise known as 'PMS'. Commonly you could experience symptoms of PMS such as headaches, bloating, irritability and generally feeling more emotional than normal. We all know how it feels! Maybe you have that 'my period is coming soon' feeling? Usually, you can experience PMS three days prior to getting your period. Keep in mind that your diet, caffeine and stress can, in fact, increase the intensity of PMS symptoms.
Period
Day one is the start of your cycle, when bleeding begins. You’ve probably wondered, ‘why do we bleed?’ As your egg wasn't fertilised, the lining of your womb sheds and leaves your body through the vagina, which explains the blood.
On average, periods generally last between four and seven days, with the heaviest days being the first and second. An average cycle lasts 28 days but can range from as few as 21 days to as many as 35 days. You can predict yours with the period calculator.
Keep in mind that you need to consult with your doctor if your period lasts longer than seven consecutive days.
Peak Ovulation
Ovulation is the period when you ovulate and are the most fertile. This is the best time to get pregnant and the fertile window length lasts about 6 days. In a 28-day cycle, ovulation typically occurs on day 14. Our ovulation calculator will help you track these days!
The first step is to work out the length of your average menstrual cycle. Day one of your period is the first day of your menstrual cycle. The last day of your cycle is the day before your next period begins. If your cycle lasts up to 28 days, your ovulation will be around day 14 (two weeks before your next period). This information will help you calculate your future periods.
Your next period will likely start about 28 days after the first day of your last period, but this can vary depending on your menstrual cycle length. The average cycle is around 28 days, but it can range from 21 to 35 days for adults and from 21 to 45 days for teens. To calculate your next period, note the first day of your last period and add the average length of your cycle to that date. For example, if your last period started on June 1st and your cycle is 28 days long, your next period should start around June 29th.
The Always Period Calculator tool simplifies this process for you. Just input the first day of your last period and the typical length of your cycle, and it will predict the start date of your next period. Keep in mind that stress, diet, exercise, and other factors can affect your cycle, so these predictions might not always be exact.
Calculating your first period can be a bit tricky since it depends on various factors, including genetics and overall health. However, there are some signs that your body is preparing for menstruation. Typically, most girls get their first period around 2-3 years after their breasts start to develop and about a year after experiencing a growth spurt.
You might also notice the following signs a few months before your first period:
- Growth of pubic and underarm hair.
- Increased vaginal discharge that is clear or white.
- Occasional mild cramps or discomfort in the lower abdomen.
Since the timing of the first period can vary greatly, it’s essential to keep track of these developmental milestones.
There are several signs that your period is about to start, commonly known as premenstrual syndrome (PMS). These symptoms can vary from person to person, but they often include:
- Swelling or tenderness in the breasts.
- Mild to moderate cramps in the lower abdomen.
- Feeling of fullness or swelling in the abdomen.
- Irritability, mood swings, or feeling more emotional than usual.
- Breakouts or worsening of acne.
- Feeling more tired than usual.
- Migraines or tension headaches.
- Cravings for certain foods or changes in appetite.
These symptoms typically appear one to two weeks before your period starts. Keeping a menstrual diary can help you recognise patterns in your cycle and predict when your period is likely to come.
A missed period can be calculated by comparing your expected period date with the current date. If your period is late by more than a week and you have regular menstrual cycles, it could be considered missed. Here’s how to calculate it:
- 1 Determine the length of your typical menstrual cycle: For example, if your cycle is 28 days long.
- 2 Identify the first day of your last period: For example, if it started on April 1st.
- 3 Add your cycle length to this date: April 1st + 28 days = April 29th. Your next period was expected to start on April 29th.
- 4 Change in cervical mucus – You'll notice your discharge increases in volume and becomes thinner, stretchy in texture, and clear in colour, resembling raw egg whites.
- 5 You may experience bloating.
- 6 You could have tender breasts.
- 7 You may notice a sudden spike in energy levels.
If today is May 7th and you haven’t had your period, it is about 8 days late. Several factors can cause a missed period, including stress, hormonal imbalances, significant weight loss or gain, excessive exercise, illness, or pregnancy. If you have concerns about a missed period, it’s a good idea to consult with a healthcare provider to determine the underlying cause.
