Is it possible for me to have a hormonal imbalance and be fertile?

Last year I got pregnant on my first try, had zero issues or complications with my pregnancy. My periods are closer together than most people but I bleed regularly and never miss my period. However I tend to show all the symptoms of have a hormonal imbalance minus the infertility. I never really thought but about it but I am convinced having a hormonal imbalance has caused many things in my life that I couldnt really explain. I have very small breasts in comparison to my body. My hair is thin. I have bipolar disorder and have shown signs of it since I was 9 and going through puberty. Aside from the i also have regular mood swings more resembling period mood swings. Irritability. I have a very large but and thighs and broad shoulders. I feel tired most of the time
