Odd period

So AF was due Friday and I only had very light pink mucus spotting when wiping Thursday night. I usually have 5 day periods and 2 of them are pretty heavy. Friday was moderate and this morning was kinda moderate and now it’s just spots. All brown blood nothing red. No cramps or anything like normally. Should I chalk it up to just luck of the draw or what? I’m not sure how many DPO bc I didn’t keep track properly. If I had to guess then maybe 13-14 DPO as of Thursday.
