Irregular periods while TTC

My husband and I have been actively TTC #2 since December and no luck yet. (I know it is still early). I have been tracking all fertility symptoms and using opks religiously but am not temping because I am a shift worker.  I discontinued the NuvaRing at the end of August so my first non-artificial period was October. I am wondering if these cyles are hindering our conception? Any ladies have cycles that went back to "normal" some time after discontinuing hormonal birth control?
