## What does your first period look like?

Getting your first period is full of excitement and anticipation.

But what does your first period look like? It’s a question on a lot of girls’ minds.

Most girls get their period somewhere between the ages of 10 and 13. Don’t worry if you get yours earlier or later than your friends. Everyone is on their own schedule, and there’s no “good” or “bad” age to get your period. But when it does come, it’s pretty exciting!

You go to the loo – and TA-DA!! There it is. Period blood. But it may not be that straightforward.

[Your first period](/en-gb/period-hub/first-period-and-puberty/what-is-a-period/ "Your first period") (and the next few after that) may just look like brown spotting in your knickers. It’s not the red blood you may have been expecting. So what actually DOES your first period look like?

Your period will last between 3 to 7 days. Once your menstrual cycle is more predictable, your period will come regularly, about every 28 days. You may want to mark down on a [calendar](/en-gb/period-tracker/ "Calendar") when you get your first period.

This way, you’ll have some idea when your next one will come. Your period will likely be [irregular](/en-gb/period-hub/first-period-and-puberty/home-remedies-for-irregular-periods-in-teenagers/ "Irregular") at first. It’s totally natural. It can take a while for your body to settle into a regular cycle.

Puberty is a time full of exciting changes.

There are a few [signs](/en-gb/period-hub/first-period-and-puberty/when-does-puberty-end-for-girls/) to look out for that signal when girls hit puberty. The first is usually the development of breast buds, small mounds of flesh under the nipple.

[Breast buds](/en-gb/period-hub/first-period-and-puberty/when-does-puberty-end-for-girls/) can be very sensitive when they’re growing. Many girls prefer to wear soft, comfortable fabrics during this time to avoid any additional irritation. It may be time to start wearing a bra.

Visit a shop for a fitting to determine what size bra works best for you. And don’t forget to have fun! Bras come in lots of fun colours and designs.

Breast buds will continue growing into fully formed breasts. Breast development continues until age 17 or 18, even after the end of puberty. It’s good to know that your breast size is mainly influenced by heredity.

Once puberty is complete and breasts reach their adult size they will continue to vary in shape and size over a woman’s life.

When you’re pregnant, every little change in your body takes on greater significance, and you can read each of them as a sign of what is happening with your baby. That is great, as long as you don’t over-interpret, or assume everything is an indication that things are going wrong! The same thing applies to your discharge.

When you get your first period be sure to [tell your mum](/en-gb/period-hub/first-period-and-puberty/how-to-explain-periods-and-puberty-to-your-daughter/ "Tell your mum") or a trusted adult. (No one will know you have your period unless you tell them!). It can be good to tell them, so they can help support you and provide you with what you need (period products, tips…).
<br/><br/>
Next, you’ll want to put on a [sanitary towel](/en-gb/feminine-products/sanitary-towels/ "Sanitary towel") in order to absorb period blood and protect your knickers and clothing from it.

[Puberty](/en-gb/period-hub/first-period-and-puberty/when-does-puberty-end-for-girls/) ends for girls about 5 to 6 years after it starts. Puberty starts for most girls between the ages 8 and 10. This means that puberty ends for girls between the ages 14 and 16.

But don’t worry if you’re a late bloomer! It’s typical to start puberty any time before age 14. Of course, this also means you’ll end puberty a little later.

However, these are pretty big ranges. When puberty ends for girls depends a lot on the individual. Each girl is different and unique.

Things like genetics (ask other female members of the family what they experienced during puberty) and environment have an impact on when puberty starts and stops.

Now, figuring out when your next period will come is easy as pie. Starting on the first day of your last period, just count out the average number of days between your periods (aka your average cycle length that you calculated) and that gives you the projected start date of your next period.

Voila! Now you know how to calculate your [cycle](/en-gb/period-tracker/ "Cycle"). Calculating your period isn’t an exact science but knowing how to calculate your menstrual cycle will give you a good approximation of when your period will come. 

Your period may not come regularly. In fact, when you first start menstruating, it’s totally normal for your period to be irregular. It may take up to a year or two for your body to get into a regular pattern so keep on tracking. 

Did all this make you a little cross-eyed? Don’t worry. You can use the [period calendar](/en-gb/period-tracker/) on this website. Knowing how to calculate your menstrual cycle is a big help for being prepared and confident around your period.
