is it Implantation bleeding?

My period isn't due for 2 more weeks my ovulation ended 2 weeks ago. I had sex 2 days ago for the first time in a month and today I had a super light pinkish when I wiped after peeing. It can't be my period because my periods are always super heavy with really bad cramps.  Could it be Implantation bleeding even though the unprotected sex was only 2 Days ago? I'd really appreciate some feedback! Hoping I'm pregnant but is it too early?
