11 days late.. opinions?

Jade

So as above I’m 11 days late for AF, I had brown spotting ( I guess it was very light) for 10 days until Saturday 17th and have had really horrid left pelvic pain? I had a pregnancy test done last Thursday which was negative.. I’m going to doctors today for blood test but out of curiousity I’ve taken a cheapy test this morning... what do you guys think?
