Period ? Implantion ? Should I test ?

So I always have regular periods every month for about about 5 days . I got my period as normal on nov 7th-11th normal flow and all . I ovulated on nov 21 , in which I was currently sexually active that week . My partner and I did the method of pulling out . However on the 29th evening I had a milky like brown discharge . Through the night nothing clean and then on the 30th o light light brown /pink when I wiped i took a test and it was negative . which only lasted til Sunday morning . Since Monday no “spotting” nothing just a milky discharge . I have been very tired and headaches and fatigue . Did i take it to early . My period is due today the the 6th and no sympotoms as of yet should I test today ?
