Is this implantation bleeding? Confused all new to this does this look like it.😩

I have posted this before but, didn't get anything out of it. My SO and I been having unprotected sex in our fertile week that's for sure but, don't know exactly when I had ovulated. According, to this app we had sex on ovulation day. My period isnt due till June 5th. According to this app which is always not accurate I was 5dpo yesterday. Last night I went to the bathroom and wiped and I was about to fold the toliet paper when I saw this light pink spotting (sorry if it's kinda hard to tell) it's because am at the hotel and they have tan like colo

r. I wiped again and nothing. Yesterday I had light cramping not to bad. I hadn't had sex for 4 days and I looked for cuts but nothing. What could this be?
