I need opinions!

11-13dpo I had spotting that ranged from brown to pink with stretchy cm. I am now 15dpo (1 day late) no spotting yesterday on 14dpo ir tiday but BFN yesterday. Do you think it was IB or the start of my period? I've been dizzy, thirsty, headaches and sore breasts (until today). Did I test too early or maybe my period is coming? Usually when I would spot prior to my period it would continue until I got AF full blown. This month it tapered off at 13dpo and was almost non existent. I never needed a pad or anything it was only on TP. My cervix is also high and soft. TIA for all advice or opinions!
