Infertility Concerns

Hello, I'm posting on here for some much needed advice. I am currently going to begin my Junior Year of college. Back in my Junior year of high school, I developed an eating disorder..I limited my food intake and lost a lot of weight..I think it was mostly caused from the enormous amount of stress I felt that year from AP classes, extra curriculars, and college prep.. Anyway, I struggled with the issue and became dangerously thin, but got help senior year of high school. I'm 5'5" and was down to 89 pounds. By the end of senior year however, I weighed what I believe to be more around 96. I've since then led a normal college life and have gained more weight. Like I said, I'm an upcoming jr. in college and I weigh right around 104 pounds. I still have mild concerns about body image but for the most part, am just happy that I'm back to normal and eating is not so much an issue for me anymore. The problem?? I lost my period back in Jan. of Jr. year of high school and HAVE NOT had it since then. I thought after gaining 15 pounds I'd get it back...I'm just so worried and concerned that I will be permanently infertile. I don't want to bring it up to my parents because I don't want to bring back the pain and horrible strain it brought between my mom, dad and I back in High School.
Just for history sake, sophmore year of high school I weighed more around 115ish if I remember correctly...could I still just not have gained enough back? I had 3 days back a few months ago of mild spotting...but other than that nothing. Any information or advice would be greatly, greatly appreciated. Thank you so much..

Keep your weight at bay but trust me your EGGS are still young and In Vitro Fertilization will make it happen if you don't get pregnant when you decide to do so. Im 41 and wished my eggs were younger. My sister in law never had her period... well.... almost never and got pregnant with IVF right away just because she is younger (33).... So DON'T WORRY!!!!
