Please don't think that a terminated pregnancy 6 years ago has anything to do with your challenges currently. Polycystic ovarian syndrome is treatable if you are committed to making some lifestyle changes. First, I recommend following your doctors treatment plan. He might recommend a laproscopy procedure to clear up some ovarian cysts. I just had this done and it was largely simple and painless.
Then, he might recommend some dietary changes to address the insulin resistance associated with pcos. Avoid eating and drinking sugar and do some regular weight lifting. This can do much to reverse this disease.
In addition, some drugs like metaformin can help get your cycle and hormones back to normal. Avoid hormonal birth control pills because they aggravate insulin resistance and further damage your ovaries.
This disease can cause some torsion of the fallopian tubes but the laproscopy can straighten them out. There is a book called "Taking Charge of Your Fertility" that will help.
It can sometimes take a good six months to get your body ready for pregnancy so stay focused, take care of your body and educate yourself about the condition.
