What do people think ?

OK so my periods are pretty regular but with out noticing I wasn't on it was only until I checked my calendar and I was 2 days late my boobs are usually by tender about 3 days before I start my period but hadn't noticed they wasn't any way I'm now 5 days late a have had slight cramping but nothing major but yesterday I noticed I had leaked it wasn't till afterwards it looked like a pinky colour almost like a salmon colour and that would have been me 4 days late sorry for the essay :) but has anyone got any advice ? Much appreciated
