100 lbs??? you know that's just a number! the human body does not work with numbers... but you're period normally starts when you hit puberty and in puberty you gain weight, so you will probably be 100 lbs soon enough.
Also, people who are anorexic, and probably weigh less than 100 lbs, don't get their period but that's because they are seriously underweight and sick.
Hope I helped.

i weigh 85 pounds and ive started

I have a strong feeling that that is not true, I got my period, and I only weigh 90 lbs. Also, if you are 15 and you only weigh 65, then you really need to put some meat on those bones!

im a guy and even i kno that thats not true, ull get it sooner or later

no you dont have to wheigh 100 lbs to get ur period cuz my friend doesnt wheigh even close to that and she has it

no, thats not true. I got my period when i was like 85 pounds and my friend got hers when she was about 70.

You are a bad liar......


65 lbs at 16, sad....I read you would be dead at that weight.

Especially for that age.... dumb.

haha im 13 and i am like 61 lbs... i dont think thats true cuz i deff. have longlonglong ways to go. i doubt it.

Not at all true. I still haven't hit 100 pounds and I've had my period for a few years now. Perhaps you heard that you won't get your period if you are extremely underweight, which is true.

no that is a old wives tale

If that were true, I would not have gotten my period at all as a teenager. This is a menstruation myth.

Your body will menstruate when it is ready to start. This depends on a number of things, including diet (which is where the weight limit comes from, though it's an old wives tale).

It is true that you can stop menstruation if you are underweight or have very poor nutrition, as your body does not want to use the limited resources it has on the intense process of menstruation. As long as you are healthy, that is what matters most.

i weighed about 90 lbs when I got mine when I was 12.

You do need to be a certain weight, but at 15, you are far under your ideal weight

You need a certain percent of body fat to have your menses. So if you weigh 100 lbs but your percentage of body fat is low (I think below 15%) you won't start your menses. Some athletes in top condition (Olympic competition condition) will actually stop menstruating because their body fat percentage is to low.

Nope, this is just an average weight so people could better estimate the on set of ones period. I was about 70 lbs when I started my period. So it is really different for everyone but researchers were able to come upon an average weight. It really just depends on your body.

Yes, it is true.

Somewhere around there, I was about 94 lbs when i started.


and why are you 15 and 65 pounds?
