Are you a pre-teen/early teen and want to know when you should start lugging pads and tampons around? Then you've come to the right place! Please remember that not all results are accurate as everyone is different and first periods are unpredictable!

Can you estimate me pls? Hiii I am 13 years old and my mom got hers at 12.I started getting discharge around 6 to 7 months ago and it slows down sometimes and then when it comes it's a lot. I had a growth spurt 4 months ago but now I'm having another one. I have headaches and one time I had them really bad for a week and a half straight. I have mood swings every day I be getting frustrated, angry, or crying over the littlest things , and I have been arguing with my sisters. I have cramps every day and its sharp pain and it hurts but its manageable for me. Also my side where my hips are have been hurting so badly it hurt to walk or stand up. I have armpit hair and pubic hair for 3 years and they are both long thick and curly, but my arm hair is long, curly but thin. And I am on stage 3 breast. I think if you you are a year younger or older than your mom your period will come soon. And I took this test yesterday and it says I got 2 or 3 weeks. And my face has been getting oily and I have been getting more pimples. Also my older sister says I'm getting close but that was 2 months ago now I'm closer

Hi I was wondering if I could have a estimate? I’m 11 years old (almost 12) my mom got hers at 12. I started discharge about 5 and 1 half months ago. I have lots of discharge but now it seems to be slowing down a bit. I had a few cramps when I started discharge but now I’m having them bad and a lot. I’m having lots of headaches too. I recently went through a growths spurt and might be in one now. I have mood swings all the time. I sweat a lot and smell. I have dark long and start hairs in my pubic area. I have some long brown hairs on my legs (same for my arms) and my arm put hair is getting long and curly. My breast have gotten much bigger in the past few days.

For 45% you are: So how long before you start to menstruate? (That's the scientific term for starting your period, if you didn't already know.) The answer is, six+ months! You're almost there! You should start talking to your mother or a trusted older female about periods and how to deal with them.

So how long before you start to menstruate? (That's the scientific term for starting your period, if you didn't already know.) The answer is, more than two years still to go! You still are very young. Don't worry, you won't need to lug sanitary products around with you for a long time yet! These are the test results I will estimate in a minute!
