Can You Predict When You’re Going To Get Your First Period?

There are some good surprises and then there are those ones that you wished you were more prepared for. I’d say that periods definitely fall into the latter camp for a lot of us. Don’t get me wrong: Periods are a perfectly natural thing that we shouldn’t be embarrassed about. That being said, I think most of us would appreciate a heads up about when they’re coming to save us the stained underwear and pants.


If you haven’t had your first period, then you would probably really appreciate knowing when it’s going to come so you could try and get prepared for it. Because there’s nothing like discovering that you got your period during your afternoon math class when you’re wearing white pants. Yup.

If you’re wondering whether you can actually predict when that first period is going to come, we break it down for you.

Tell me straight up: Can I actually predict when I’m going to get my period?

Sorry, but science has not come up with a 100 percent accurate way to calculate the first day that you will experience the joys of menstruation. Yet.

So, does that mean it’s going to be a big surprise?

Not exactly. We may not be able to find out the precise date and time we will get our periods, but there are a number of ways you can figure out when your period is going to come.

Like what?

One helpful guideline can be looking at when your mom, sister, or even your aunts and cousins got their periods. It’s not a foolproof method because various lifestyle factors can impact when you’re going to get your period, but it will hopefully help give you an idea about whether the women in your family tend to get their periods earlier rather than later, or vice versa.

Anything else?

You bet. There are a number of quizzes that you can take to help give you an idea about when yours is coming. Of course the accuracy of them isn’t 100 percent, and some are better than others, but at least it will give you the sort of idea.


What’s more, you can also look at when you started puberty. reports that periods generally come two to two-and-a-half years after boobs start developing. Also, factor in when you started growing pubic hair, how much you have, if you’ve started sweating more, and if you decided you needed to use deodorant. These are all changes that occur to your body during puberty.

What about symptoms to look out for?

When it’s getting closer to your period, you will probably notice some vaginal discharge in your underwear. It could be clear to whitish and it will usually show up about six months for your period.

Another thing that might happen is that you experience some spotting (aka a few drops of blood) in your underwear. It might be a lead up to a bigger period or it could even be your first one.

Anything else you’d like to add?

Be aware about whether you’re experiencing PMS symptoms. Everyone’s body is different and PMS symptoms can change over time, but keep an eye out for things like bloating, cramps, moodiness, breast tenderness, changes in appetite, or headaches. You might mistake some of the symptoms as a cold or feeling under the weather, but be aware that it could be other options.


And remember that whether your period comes early or later, it really isn’t a big deal. Everyone’s bodies are different so don’t sweat it if you got your period at a different time than your friends.
