IB or AF?

Saturday night I was 7dpo and got bright spotting (not pink, it was red). I though AF had started early so I put a pad in and went to bed. When I woke up, nothing. Kept a pad in all day, I got home around 3 and checked (hadn't had a chance to pee all day/bridal shower), and there was this dull beige, no blood. Went to bed and woke up this morn, same thing but less. Went to the bathroom just now, same thing. No cramps or other symptoms. AF isn't due until the 1rst. Screenshot below is from 7dpo, couldn't get the whole chart in
