In need of advice !!! 6 days late

mariah
I'm 6 days late on my period. And for those 6 days I have had A LOT of cervical mucus/discharge that's sticky and like egg whites. It started the day I was supposed to get my period. I've been having weird not really period cramps but cramps. And I've had what feels like indegestion or heartburn along with slight nausea. Do you think I finally got my BFP??? Advice please!!? I don't wanna test yet cause I don't wanna see the screen say NOT PREGNANT on it . It's so disappointing to see that month after month
