PCOS is an endocrinological disorder, it doesn't just effect fertility. It effects the whole body. With PCOS you have a higher risk of heart attack, high blood pressure, stroke and uterine cancer, high cholesterol, nonalcoholic fatty liver, and diabetes. Of course not everybody will have those issues. With PCOS its important to maintain a healthy lifestyle, eating right, working out and keeping your weight at a normal level.
Some women with PCOS, not
EVERYBODY with PCOS will have polycystic ovaries. Some get ovarain cysts. I've had PCOS symptoms since I was 13, I was diagnosed with PCOS at 16.. I didn't have any ovarian cysts for 7 years, now I'm getting cysts out of nowhere. Ways they diagnose PCOS is an ultrasound, your ultrasound may come back completely normal but you still may have PCOS. Women with PCOS tend to have an elevated; LH/FSH ratio and a high testosterone level. Some have insulin resistance.
Besides irregular periods do you have any other PCOS symptoms? I'd also bring up to your doctor that you've been TTC for over a year. They can give you Provera to start a period, and Clomid to help you ovulate. If you have any questions about PCOS feel free to PM me.
