Question ladies need advice please!

I’m 12DPO I haven’t been tracking my ovulation this month but around times I know when I’m ovulating, tested all last month’s positive clear blue

However this month I decided not to test. All my cycle apps show 4 & 5 days til AF. I had 2 pads filled with dark brown blood. Then today I wipe and it’s light pink. No cramps at all only sharp pain in my waist area left side.

I showed an picture of the pink blood I also have an pics of the dark brown blood that filled pads. It’s barley any blood now & very emotional. Any thoughts
