Confused some one tell me they had this

So I’m due my period tomorrow and yesterday I pink Cm just two blobs picture here

Then I had sex with my partner and when I cleaned my self up and wiped I had his seman mixed with a bit more pink blood I thought straight away he had jumped started my period so I put a pad and and nothing no blood nothing! So I’m thinking this is implantation bleeding as the blood was up inside me and not had anything since I also had cramping yesterday what do you guys think? Racking my brains now cos I have never had this in my life
