Implantation? 🤔

So I supposedly ovulated between the 23-27th of April and on the 23 I had unprotected sex but the guy said he pulled out. (Not my bf or anything just fwb) a few days after I started spotting which was weird because I never spot in the middle of my cycle.. let alone during my fertile window, but because it said I ovulate on the 25th.. I figured maybe my body is starting to show signs when I ovulate. But then on May 1st I started spotting again.. so now I’m thinking this actually may be implantation spotting 😐 this is what it looks like when I wipe.. it hardly ever goes on the panty line and since May 1st it’s been starting and stopping. (Sometimes, through out the day, I wipe and it’s there sometime it’s not) does this look or sound like implantation to anyone? My period is due in 6 days.. should I take a first response test?
