Not to sure..

I was supposed to start my Period October 31st it is now November 9 I am roughly 10 days late.

A couple days ago I had some brown discharge for a couple hours then it stopped, next morning I was all ready for my af but nothing n still nothing till today I went to the washroom and noticed pinkish discharge, also last week I vomitted once and I'm always tired I've been having mild cramping as well . I haven't bought a pregnancy test cause every time I do I always start the same day.. any of you had the same problem
