PLEASE HELP ME UNDERSTAND!!!

Missty

Ok so it is now 4 days before AF (Aunt Flo - menstruation/period) and I just woke up having light pink spotting what could that be? It went away after a few wipes I even stuck the tissue inside of me to see (I know tmi) and there was nothing...and I forgot to mention that I'm also having a creamy white discharge since yesterday (not on tissue but when I try to check my cervix..and my temp was 97.9 this morning..also for like the past almost 2 weeks I've been experiencing tender breast (not to touch but on the inside) on and off every day.My DH keep telling me I'm pregnant but I keep getting BFN when I take a test for the past few days including this morning😢 I'm so confused
