HELP TRYING TO GET PREGNANT?

Me an My boyfriend have been trying for 7-9 months and not getting any results so i've went to three doctors during that 7-9 mo. gap. first one I had diagnosed me with dub (Dysfunctional uterine bleeding) due to hormone imbalance, because i would come on my period and stay on for 3 weeks or more. I honestly thought it was normal because heavy bleeding prolonged bleeding runs in my mothers side of the family. But of course i was wrong, she gave me birth control pills to balance my hormones and she claimed that this DUB shouldn't have been stopping me from getting pregnant,she told me to take the bc for 3 months and to just eat healthy and i'll be fine. I did that but after still no baby and my DUB is still here. The next two doctors said the exact same thing. Now i recently met a new doc who better explained to me what was going on "thank god" she said that I have a high level of testosterone and the fact im overweight is not allowing me to ovulate sadly and she said its also a possibility of PCOS she basically prescribed that I take bc but also explained there's no way to know how long it will take for my hormones to act right. I said i'd do it but while im doing it i want to help my body balance hormones and loose this weight. I'm 5'3 and 230lb, I know it sound like alot but if you'd seen me you wouldn't know thanks to the testosterone i have alot of muscle alot of people say I look 170 or 180, but anywho just please help me somebody can you give me tips on what to do what not to do teas and herd and all that good stuff I'm really aiming to be preggo by late december or early january??????
