93 days late but test is negative!!!

So my period is 93 days late! My cycle for the past few months has been 40 days and the longest I ever went without my period is 43 days until now. 93 days! I have no signs of my period even starting at the same time no signs of being pregnant! About 3-4 weeks ago I went and got a urine pregnancy test at pregnancy solutions it was negative and I'm feeling fine. I don't feel sick or like something is wrong with. I'm just so confused!
