Implantation bleeding ??

Okay so I had my period august 15th-19th and on the 20th, 21st I had EWCM, and bad cramps , I’m assuming I ovulated just days after my period. We had sex many a times on and around my period.

I’m now on cycle day 17 and have had slight cramps and VERY LIGHT pink spotting only when I wipe since Sunday ..

on Friday and Saturday (aug 26th/27th)

I had what seemed like a cold (runny nose and such) for those two days then the Sunday (august 28th) was when I started spotting ..

I did stop bc 2 months ago and with my first pregnancy I also ovulated just days after my period ..

my question is does this sound like implantation bleeding ? Or what ???
