Your period should start today ..? lmao what's wrong with me?

So my period is late .. HELP? 
I called my clinic and they suggested that I wait to see if it comes this week but it's already Wednesday.. so I'm not stressing out about it really .. I'm just constantly thinking about it hahahaha anyway yeah I'm scheduling something for next week if I don't get it Saturday ... I'm in between wanting to be preggers and not getting my hopes up. .
