Anyone ever had false negatives?

So I was just replying to another girl when I counted exactly how long it's been sense my last period ended and it's like 61 days😱 That seems really long, even though I've never been the most regular girl. I've taken 3 tests in the last week from different brands and they are all negative. No cramps or bleeding or hormone craziness. Thoughts?
