Estrogen

I've been having estrogen problems ever since I was a little girl . I have an extreme irregular period I. I usually get my period every 6 months and that's luck . I got pregnant once in my life when I was 23 yrs old . Unfortunately had a abortion. Ever since then I've never came out pregnant again . Iam where that I have high estrogen and is extremely hard for me to get pregnant . I need some advice on what can make my fertile system get better ?
