45 Day Cycle/PCOS

Ok so my period is all willie wonka since July of last year but it has only been 43 days once. My current cycle is going on 45 days which is not normal for me my last period was May 30th it is now July 13th.... My husband an I have been trying to concieve for a year now in February I was told that my testorone levels where slightly high and that if I wanted to get pregnant I need to lose weight. Than on May 29th my Dr told me that I might have PCOS.... anyways I took a pregnancy test at a follow up appt I had on the 11th of this month and it was negative but 2 days later and still no period I don't know if I am either pregnant or my eriod is playing with my emotions and will come in the middle or end of this month. But my cycle being this long is just weird and unusal for me... Any advice or comments on what I should do or think maybe wait it out for the remainder of this month or start testing at home like a crazy person...
