Raindrops12

I am 27 unmarried girl. My problem is irregular periods. I got my first periods at the age of 14. After 1 yr only got it at the second time. for 3 years it was like that. once in a year. then it came once in 6 months. My doctor said that i am anemic. i had some tonics. but still it is not regular. now it is once in 4 months. I took Himalaya Eve care for 3 months. then tried gynovit. Nothing works 4 me. I am so deppresed abt this issue. Please advice me wat to do
