If I quit my bulimia today, how long before I get my period back??

I've been bulimic for about a year and I have not had a period in over 13 months. I'm 16 yr old, 5'8, and currently 130 lbs. At my lowest I was 121. I used to keep my weight around 125 even though I constantly binged but now it seems like I have gained a few and am stuck at 130. I'm also taking estrogen pills right now that I got from my OB-GYN but I did not tell her that I was bulimic.
So I want to know...If I quit purging today, when can I expect to get back my period?
Please help...I don't know what to do.

See the doctor! I was bulimic before but I had regular periods. Stop it now, it is never a good thing to do. I do exercise and I loose more weight. See the doctor, don't be shine, it might no be because of you are bulimic.
That's a good question for your doctor.
You need help to stop purging. Speak to your guidance counselor or someone else who you trust. If you get the help/support of an adult, it will be much easier to stop knowing that you're not going through this alone. Good luck!
actually, you really do need to see a doctor...but first, come see me
