Maxim do you have a period every single month or have you been known to skip a month or two? If your periods are regular and you don't skip it's not likely you have annovulatory cycles however depending on stress you may O at different points each cycle!
Doesn't hurt to talk to a doctor but depending where you live they won't do clomid without a hormone panel first and some other hoops to jump through which I think would stress you out further so be sure you aren't just delaying your own O.
Robin is correct in the states it's at least 6 months of active trying. In my case I was already under the care of an RE because he unclipped my tubal ligation. He did a hormone panel off the bat and said I was healthy normal and good to go so 6 months later when I came in complaining that's when he prescribed Clomid. Try and remember I was CD 18 before ovulating with DD3, I was like 40 days into a cycle thanks to an anovulatory month with DD4... Robin is also 18 DPO and just now ovulating, and what should give you some hope is she is swaying pink.. and while I wasn't swaying pink mine still ended up pink. The longer it takes to O it seems better shot at pink.
