I'm 4 days late and I'm almost certain it is because I am stressing. I had sex on what I think is the last day of my fertile window (or not a day of it at all) and then 3 days afterwards. I'm bad at keeping track of my periods especially since it is still irregular and Im busy with school! We used a condom the first time but then we depended on withdrawal. however, I took plan b both days afterwards and although I'm 5 pounds above the 'weight level' I'm most certain I am ok. 

so how do you de-stress to make your period come?!
