Not ovulating, No periods :(

Anyone else in this position? I came off pill in Oct last year, had 2 periods, started TTC at Christmas - and no periods since. Not pregnant but doing regular ovulation tests and not ovulating either. Went docs he told me to go away and come back at end of March. I know it can take a while for your body to get back into a cycle but it's very frustrating. :( feeling confused!
