Do i have a hormonal imbalance?

i'm going for my annual physical very soon so i'll ask my doctor anyway...but is there a possibility that i have a hormonal imbalance? i have a lot of dark body hair over my body (mostly stomach, back and chest/) and my are different sizes. i kow that this is normal when one is still developing, but they are at least two cup sizes different. i read that that can mean a hormonal imbalance, as well as the body hair. also i have acne. not just a few here and there, but it seems to come in waves all over my face. it's not extreme but it still seems like a lot. and i have irregular periods. last summer i was having them ever other month, for 3 weeks at a time and my flow was VERY heavy and i couldn't even walk or sit up in a chair without leaking. i went to the doctor for this, and they had some tests done but they didn't do a hormone test. they did find out that i had anemia (which of course i did i was pretty much bleeding dry!) but they didn't do anything about it besides recommended that i take a daily multivitamin. eventually my periods got almost regular, i only bleed for a week and either every month or every other month depending. and i don't bleed nearly as heavy. i also get extremely depressed and this might be because of my lifestyle, which is changing for the better soon, but sometimes i feel like i just can't stop it. could i have a hormonal imbalance?
