help.......

so ima try to explain this the best I can, I ovulated on the 21 of Jan, my period was due the 4th of February.

I was experiencing some symptoms and tested negative THEN finally AF came 3 days late.... on the 8th (16DPO) it was bright red and filled a pad... USUALLY My periods are 5days long or longer. But for some reason this time it was only 2 days long;bright red. ever since then for the past day I’ve have this brown discharge no cramps or anything just this ...

is it just part of my period? I’m so confused because I’ve never had this happen. I keep using a pad because I’m just waiting for my period to get heavy again since I never have it this short ... is it normal for it to just go from bright red to this?
