Implantation bleeding or light period

About 2 nights ago I woke up and when I went to use the Bathroom and wiped. There was this light light very pinky blood on the tissue. So I put a tampon on and called it a night thinking it was my period. I woke up and the tampon was white. So I brushed it off. Today when I used the toilet I wiped and a little bit of light pinky blood was there. So I put a pad on and when I went to use the bathroom hours later it was again white. No spots no blood. I took it off and headed out to pick up my fiancé. When we got home and showered, we got ready for sexy time. BUT when we were in the middle of sexy time he’s like baby are you getting your period ? I was like I’m not sure at this point cause well of the confusing blood. When he wiped off this penis the blood was light pink blood and I wiped, it was also light pink. So now I’m sitting with a pad on. Also my period is about 5 days late.
