confused

Well I just think I probably left alot out of the first post so here I go again. As I said I had my IUD removed two months ago. I have a cycle a week later. So I marked it on the calender so that I could start seeing how many days my cycle is. Well 28 days rolls around.... nothing 30....35.....38 days and still no cycle. I had one day of spotting on June 2 but that was over by mid day. So my research begins and it says that my most fertile day would have been June 1.... What gives.... Thought the spotting might have been implantation bleeding but surely I would have gotten a positive test by now it that was the case..... right??? 
I guessing its just a waiting game at this point.....
