16 days late and BFN!!!

Ci
So I was supposed to get my period on May 5th and nothing. Up to this date I still haven't had my period.
​I took a pregnancy test the (digital one) and says not pregnant. 
​Is there anything I can naturally do to get my period. I just want it to come so I can start a new cycle. 
​Currently I'm on CD59. Yeaaaa can you believe that?! For the past 4 months my CDays were regulated to 41-42. Now this just threw me off. 
​Any suggestion guys?
