Please help is this implantation

I had sex with a condom and he pulled out. Condom never broke also. My period is due on Wednesday but my cycle used to be 24 days, but for the last months it’s been 27 days. Today (my 24 day of my cycle) I had pink spotting. I had to put my toilet paper sorts in my vagina to see if it’ll come out, and sure enough stuff came out. I had some cramps today, acne as if my period came, and that’s pretty much all. Please help. Could I really be pregnant.
