I am a female 21 years of age, height 5'2 and weight 120. For the past four years I am experiencing very scanty periods, my periods last three days max and are very light, they do however come regularly on a monthly cycle. I have researched online that maybe I have hypomenorrhea, is this true? I took a blood test last year and everything was normal, should i be concerned? I am aware that scanty periods are not good to have especially for getting pregnant in the future. What should I do? Will having scanty periods cause pregnancy issues in the future for me?
