Vitamins

Okay so my fiance and i have decided we would really love to start a family together. We have been having unprotected sex for a year and not really trying but also not preventing either....but nothing has happened. But now we both really want it. So I went to the dr to get my hormones and everything tested and everything was good but i went to get an ultrasound done on my ovaries and turns out i have cyst on my left ovary. The dr said if i lose some weight (5'3 178lbs) it'd increase the chances but im just wondering what else can i do....like is there any vitamins that could help or any specific diet or medication....just any advice would be helpful... .
