If you find you're not ovulating, or only now and again, you may have POS (polycystic ovary syndrome). Last year, my friend who was 34, and who'd been trying to conceive for years, went to hospital for a bit of laser treatment - which corrected the problem. Her little boy is now 3 week's old! As for myself, I was told there'd never be any chance of having children, but at 41, gave birth to my first son. Just over a year later, I was pregnant again. My advice would be to see your doctor immediately, go through all necessary channels - and never give up! Good luck!
