Implantation bleeding? Help please!!

My fiancé and I had sex all last month before my period, and my period came right on time as expected. Okay, so, it came but it was pretty light but not super light or enough to alarm me I guess, but nonetheless, light. Fast forward to now. My fiancé and I had sex a few times on my fertile days with condoms and only one time without and he pulled out. So, now I'm on the last fertile day and for the past two days I've had CM with blood streaks and pinkish tint! I have never had this happen considering my period just got done almost 2 weeks ago. Idk what this means! Is my body just doing something funky or could this be implantation??? I mean does implantation happen that soon? Or what??? I think I'm working myself up for nothing... 😩
