F'd up cycle

So I'm on CD21 and I haven't ovulated yet. So I can't take my estrace. What bothers me is, what if this is am anovulatory cycle? I've never had one, in 3 years of cycle monitoring. Does that mean I shouldn't do IVF next cycle? It would definately mean I won't have taken estrace, so shouldn't I wait until a cycle when I have?
I really feel the fertility gods are f'ing with me. Just trying to keep me negative and stressed.
