When I had an eating disorder, I lost my period for 6 months, eventually, when I returned to eating healthier and more balance, my period returned normally on it's monthly cycle.
Firstly: Was your period normal at any point in time?
and to answer your question, yes, I think you should continue to seek medical attention on this and be honest with your gyno about the real details. I know you mentioned wanting children at some point and it may take a few years to get your body back to ovulating corectly, so you want to get on that as soon as possible.
Also, I don't mean to pry, but are you eating a more balance diet and at least 1300 cals. a day? That's what the body needs to ovulate, if you're not eating that kind of diet, you are affecting your fertility.
Also, how much are you excersicing. Even now, my body isn't quite normal, if I do too much excercise in a given month, my period will be late. So that also plays a part, getting too much excercise can also cause you not to have your period. This happens often to athletes.
at any rate, I hope this works out to be something that's easily fixed
