Hate being not being regular!

I've never have a normal nor regular period. But this passed May, June and even July I've hadmy Period on the 7th on the dot! I haven't gotten my period yet, I tested and it was negative :'( I try not to get to excited. On here it says I should be getting my period today the 11th but I haven't gotten it yet. Either I'm way late or I might not get my period this month. This sucks! :/
