15. Days. Late.

So I'm 16 days late. Still no freaking period. 6 negatives. Debating on taking another test to be sure. But it's just a waste because they all come out negative. There's no way I'm pregnant I wouldn't think. But like, I'm just dying to have my period. Like... Is there a way to make it come quicker? I don't have a doctor just yet , but I'm going to start looking into some. It's just irritating not having my period. Has this happened to anybody else? I'm trying to not freak out.
