PLEASE HELP!!!!!!

What could this be??? Took plan b on May 9. Had unprotected sex on May 5 and 7 but noticed a bit of blood about two hours after the sex on May 7. Here’s the thing-I don’t know if the blood was from the sex on the 7th or the 5th. The sex on the 7th was a bit more rough so I’m thinking it was from that one but I got extremely nervous so I took the pill on the 9th. He didn’t cum inside me but I was scared about precum and I got my “period” a few days early on May 19 and it lasted until May 24. Flow was lighter than usual but still had all my normal symptoms. I took clearblue digital tests on May 31 and June 4 and both came back as not pregnant. Could this mean anything regarding pregnancy? Please tell me any and every possibility of what this could mean. Also should I retest soon?? According to Glow my ovulation day was June 1. Please please help I am so so nervous and please no rude comments I know I made a huge mistake.

Also- I have not bled AT ALL since May 24.

Thank you for reading that long story I’m sorry and I appreciate any and all responses

Forgot to add- this came out when I was urinating but I was about to wipe so it fell onto the toilet paper but nothing was or is in my underwear.
