Talk to Gynecologist on Increased FSH

I'm 26 years old, unmarried, 55 kgs, height 5.4". I got my lab tests in June for which LH, thyroid, prolactin, VIT D, Hb, all were fine within the range. Only FSH was 10.88 on 2nd day of menstruation. Gynaecologist prescribed ovaflow twice daily for three months. I cut down on sugar, processed, fried all junk food following proper diet suggested by nutritionist. After three months I got my FSH levels test again, and now it is 15.1. Also when I started this course mood swings got better, but in the last two months I got cramps and a bit of increased flow.
