Irregular periods, TTC, not much help from drs

Long story short, I've always had irregular periods, had scans and cameras, with no actual diagnosis, in fact it feels like I've been discarded. Apparently I have speckled ovaries, but after the hysteroscopy came back as nothing abnormal, nothing further has been investigated. I left life to it for a couple of years, but now im TTC aged 32 and I also have anxiety and OCD so think catastrophically. Although I didnt expect a positive first time round but AF arrived today after 7 weeks and seeing that negative test has left me quite down and hopeless. My Gp has just referred me back to my gynaecologist more for the irregular rather than fertility (this is only the first cycle TTC)
Has anyone conceived with irregulars and how long did it take?
