Implantation bleeding 2 days after sex??

If I ovulated on the day or one day before I had unprotected sex (using pull out method), could I be bleeding 2 days later cause of implantation?

I had sex for the first time two days ago and I noticed white discharge first followed by light brown/light pink discharge. My cycle is 24-26 days, and my periods are 2 weeks away.

Could it be conception/implantation bleeding?
