First Period Quiz

What is your child’s age?

A) 9 and under

B) 10-12

C) 13+


What’s the average age for a first menstrual cycle?

The average age for a person to have their first menstrual cycle is 12.5. Most people tend to get their first period between the ages of 9 and 15.


Have their breasts started to develop?

A) Not yet

B) Sort of?

C) Yes


More about breast development

The beginning of breast development is a sign that a menstrual period is on its way. Typically the first period will occur two years after the first signs of breast development have arrived.


Do they experience vaginal discharge? 

A) No, what’s that?

B) Once in a while

C) Yes, it’s usually white or clear and sticky


What is vaginal discharge?

Vaginal discharge is a combination of bacteria and cells that slough off from the outer vaginal layer and mix with mucus and fluid produced by the cervix, vaginal lining, and glands at the opening of the vagina. Typical vaginal discharge is white or clear. Most people start to notice discharge happening 6-12 months before getting a period.

Do they have any pubic hair or armpit hair?

A) Nope, not at all.

B) There are a few straggly hairs.

C) Yes, there’s no denying their presence.


The lowdown on body hair

During puberty, you will begin to sprout thick, course hairs around your pubic area and your armpits. This usually happens after breast development has already begun, but in some cases it can be the first sign of puberty.


Have they recently had a growth spurt?

A) No

B) It’s starting to happen.

C) Yes, they resemble a weed.


What is a growth spurt?

A growth spurt is when your child hits their stride and the hormones in their body decide it’s time to multiply in order to get you closer to their final adult height with super speed. If they’ve shot up a few inches in thigh recently, it’s a sure sign that their menstrual cycle should be on its way. 

Do they have any pimples?

A) Thankfully, no.

B) Yes, a few spots here and there.

C) Their acne is is becoming a major topic of conversation.


Acne during puberty

Once puberty hits, they may notice a few changes to the biggest organ in their body: the skin. While they might not become a zit factory overnight, they may start to notice a layer of oil forming over top of their skin overnight. And even if they do become a zit factory, who cares? Like Justin Bieber says, pimples are cool



Do they experience mood swings?

A) Not usually?

B) I do find they’re having more ups and downs.

C) Yes, they’re struggling with more intense emotional spikes lately. 


Puberty, hormones, and emotions

Puberty can wreak havoc on a person’s emotions and leave them feeling confused about what they’re feeling. If they’re experiencing more ups and downs than usual, it may be a sign that their body is beginning to flood with hormones and puberty is well underway. Strong emotions are a normal part of growing up, but if they ever feel unmanageable, they should speak to a trusted adult or medical professional who can get them the help they need.


Mostly As

There’s a long way to go. They might be the right age but their body is working on its own schedule and hasn’t started to show signs that they’ve entered puberty just yet. Be patient. There’s a lot for them to be excited for. Once they start to experience breast development or hair growth, they will be further along on the journey towards getting their period.  

Mostly Bs

Too soon to tell. While they’ve certainly started to manifest several of the telltale signs of puberty, they may need to experience a few more before their menstruation journey begins. Try taking this first period test again in six months – some of their answers may change!

Mostly Cs

Any day now! The magical, mysterious process of puberty is already well underway in their body, which means it’s almost ready for the final frontier: menstruation. Make sure they’re prepared to get their first period by learning the basics like how to use a tampon or a pad. They may want to start wearing period underwear for teens to avoid leaks, especially if their period comes at an awkward time. You can help them prepare a first period kit so they’re extra ready for what’s to come, even when they’re on the go. First period blood is often brown and murky so let them know not to necessarily expect a smear of bright red in their underwear.
