HELP! Implantation bleeding?(tmi)

I had unprotected sex Friday the 27th , through Sunday the 29th , It says on glow I was ovulating during this time. My peroid is due in 7 days and I woke up this morning with very light bleeding only when I wiped. First wipe it was a bright red/pink color , but now it's only brown. Here is a picture of what it is now , can anyone tell me what this might be? Does it look like implantation bleeding!!
