Hello, I m an 18 year old female. I starved myself from the age of 13 to about 17, and during that time, I rarely had my period, and I was worried about my hormonal development. I read that low estrogen levels can effect bone development or cause heart issues, as well as affect fertility later on. I have since gained a bit of weight (around 5 4 and 91 lb as opposed to around 75 at the worst time) and my period has become more regular, but I was wondering whether I still had the time to develop regularly since I m on the tail end of puberty. If not, would estrogen supplements help?
