Bleeding turned into Spotting 🤔

So af is due 2mrw .... I had bleeding this morning & so I used a tampon thinking it’s HER 😪 but I went to change my tampon & it was pink with red & no more signs of red just pink ...... I felt nauseous in the morning not so much now a few dull small cramps ....

Can you implant a day before AF 🤔
