If you are severely underweight you will not have periods for the simple reason that nature protects us from pregnancy if our bodies are too malnourished to sustain that pregnancy.\n\nHaving said that, I'd agree with the above 2 answers in that as long as you are not SEVERELY underweight then it should not affect your periods.\n\nMany anorexics (and some athletes) find that their periods stop if their weight becomes too low but this is unusual and it shouldn't affect you unless you are emaciated and under-nourished.

Every girl has her own unique internal timetable. Most girls get their period from 9-16. During the year or so before menstruation starts, the physical changes that happen are underarm and pubic hair, a clear or yellow vaginal discharge, breast development, and even a growth spurt.

Get to the normal weight rang for your height and build. It helps regulate your menstrual cycle. If you are overweight or underweight if has significant effects. If that isn't;t a problem, talking to an OB/GYN wouldn't hurt. Though as a rule of thumb they make you try for a year without hormonal treatments.

Actually a woman requires extra calories when she's menstruating. Most of her weight is gained from water retention and can gain 5 or more pounds during her period, but then loses it afterwards due to the fact that it is mostly water weight (not to mention constipation).

It really depends on the women. I actually loss a pound or two when i have my period, because it makes me hyperactive and not want to eat. Most women gain one or two pounds because of water weight and cravings.

The first day of your period is day one.

It is not uncommon to miss a period if you have lost a lot of weight. It takes your body a little while to adjust.\nTo be on the safe side however have a pregnacy test.

Yes, you can get PMS symptoms, but they come generally a week before your period.  You can get bloating, irritability, cravings for sweets or salt, tiredness, and many, many more things.  As for the initial "leakage", general no, that is usual a surprise as to when it starts.  If you want to try and keep track, start counting on the first day of your period, that being day one, and keep counting through the month, when you hit about the 28th or 32nd day in your cycle, you should get your period. Every women is different, so you have to learn your cycle to get your heads up that it is coming.  Hey this got me through high school without a surprise, hopefully it helps you.

The number is always going to be accurate as long as your scale is accurate, no matter what time of day you weigh yourself.  However, you should weigh yourself at the same time of day each time you weigh yourself to have a more accurate comparison.  In the morning is best because you haven't eaten anything in a while or had anything to drink.  You usually weigh the least in the mornings so that's always a plus.

I think it's perfect. :) Your body fat is normal and plus I heard that electric scales are wrong AND the fact that our bodies gain body fat when we are about to start our period. Don't quote me on that though. :) But it's a good thing that you are trying to be healthier. Skinny doesn't always mean healthy, remember that.

You are allowed to weigh in in the nude, no one cares. Usually you are in the same room when you weigh in, so it's not like you will have privacy. But I don't think anyone will be looking at anything other than the number on the scale to be sure you made weight. Most wrestlers weigh in in their underwear or singlet unless they are trying to shed 1/4 ounce to make weight.  Exception: Girls weigh in in a seperate location.

No not necessarily. I didn't bleed my first time. Everyone is different so the answer to this question should NOT be yes.

You will know when you have your first period, because there will be lots of blood.  Before you have your first period, you will begin to have discharge at times, maybe for years before your period starts.  Sometimes it will be white, sometimes brown - this normal.

Stress & low body weight can disturb or stop you cycle completey.  It doesn't sound like you have low body weight, if your doc has put you on meds.  Your cycle should start in a week or so, every woman's body & genetics are different.
