PCOS and fertility!

I am 27 years old and have not been able to get pregnant since I was 14 and had to get an abortion...not my choice it had to happen...but ever since that happened I can not get pregnant. I have never had to use condoms and my period is usually on track. I was told by my doctor I could have infertility due to PCOS. I have tried wellness fertility blend and hormones to Balance me out and vitamins. Nothing works. I have had ultrasounds and nothing really showed in it. I have an awkward uterus and a one side is more forward then the other. My question is this, what can I do to get pregnant?? I have been actually trying for 3 years! I have just about no hope left...in need of major baby dust!
