Have you talked to your doctor about PCOS? If you're having issues with weight and fertility, that may be part of the root cause (it's one of the most common causes of fertility issues in women). You might want to see about getting tested (hormone tests, and fasting glucose and insulin test are required to help diagnose it), that way you can start addressing it now if it is part of the problem.

A low carb way of eating is definitely one of the best lifestyle changes to help with all of the above. Even if it's not, this is a great way of eating to lose weight and be healthier overall. Make sure you check out the resources on what goes on in the first week or two, and what to do to get through it. If you're switching from eating a bunch of refined carbs, then the first couple of weeks can be rough. It's normal, but it often turns people off to this way of eating, because they don't realize there's a sort of "break-in" period.

In short, for the first week or two, don't restrict calories, just eat to satiety and log your food to ensure you're eating enough, drink lots of water, eat lots of fat, and make sure you're getting plenty of sodium. Going low carb actually requires you to eat more sodium, so that your electrolytes stay in balance and you don't risk deficiencies in sodium, potassium, or magnesium.
