9 days late

So I am 9 days late for my period I went Friday for a blood test to see if I was pregnant but it came back negative. Saturday I had very light pink discharge after I wiped and I still have it occasionally and it’s now Tuesday and light cramping but not my normal period cramp pain. I tested this morning at home and it still showed negative. But Saturday when I tested me and my fiancé both swore we saw a very very faint line. I messaged my obgyn again yesterday to let her know about the pink discharge and that we thought we seen a very faint positive and was asking if this is all normal and she said it’s possible I’m pregnant but it’s basically a waiting game still. Has anyone tested positive this late?? With both my kids I already have I tested when I was supposed to get my period and they were positive so this is all new and very confusing for me.
