Hiya!
Im 5"2 and 46kg. I'm also an 18 year old female and at this same height my weight has varied from 35kg to 55kg. For the past few months I have maintained at 46kg and I feel quite comfortable with myself. Doctors I have seen all have varying opinions regarding my weight, with some insisting I gain to at least 51kg before I reach a minimum healthy, maintainable weight for my height. However I m afraid of gaining any more weight than my current 46kg and becoming self conscious again as I have done in the past when I was on the heavier side. Right now I feel comfortable and even at times confident with my shape and size. I also now have regular periods (I did not at a lower weight) and I personally think I look healthy, but would any of you say I am still considered underweight?
