You have insulin resistance related most likely to your family history (your BMI is 22.7 which is normal). PCOS is a syndrome related to insulin resistance and elevated LH is a sign as well. In your case, because of these issues, you do not ovulate predictably. This is very dangerous over the long term with regard to an increased risk for uterine cancer. In answer to your question, the Benforce (which is Metformin) is usually well tolerated and GI side effects are common. With regard to the birth control pill, common complaints include nausea, spotting and fluid retention. You will not gain weight on the pill. You need to be on the pill because it protects you from uterine cancer. You need to be on it unless you are trying to get pregnant, pregnant, or breast-feeding. It is more unhealthy to not cycle regularly that to be on the pill for cycle regulation. I hope this helps!
