Brownish yellow discharge?

Do you know what this is? I’m 10dpo and my period is due Friday (in 3 days) and I’m hoping it’s not ugly AF trying to come early. It started last night around 10pm and I thought for sure my period would come in the middle of the night since I had minor cramps but I woke up and nothing, just little tiny bits of this and then same thing this afternoon. What do you think it is?
