ttc and confused !

Hello ! So my period is currently 3 days late . I ovulated either October 16/17 ... I'm experiencing all sorts of symptoms such as nausea , I had light cramping and right pelvic pain on and off for two days, sore heavy breasts, lack of appetite, and this morning and yesterday morning very light dark brown spotting ... I've taken many tests! All morning ones seem super faint but I'm still not covinced, I took another this evening and it was negative (I know evening testing isn't good) ....
