Spotting please help!

Husband and I haven’t been actively ttc but we haven’t been trying to stop it either,

my period ended on the 22nd,

On the 26th I had pink spotting when I wiped, and 27th I had brown spotting.

Then it ended until today which is my peak fertile day, I have pink when I wipe again. What is going on? Please help I’ve never had spotting in my entire life
