Light brown cm 2-3 days before AF?

I am only a couple days away from expecting AF. Today I have a little light brown discharge on toilet paper, I go to check cervix and there’s more creamy light brown discharge. Not enough to get on panties. Has anyone gotten this and had a BFP? I’m 11 or 12 DPO. I had a negative Walgreens digital yesterday at 10 or 11 dpo. Help!!! Can this be IB or the early start of my period?? I’ve been having weird cramps, not like period cramps, a lot more milder than period. .... my head is totally fu*king with me isn’t it?!
