So we had sex two days into my ovulation period, and now a little more than a week later, I went to the bathroom to find pink discharge in my underwear and very mild cramps (almost like a pinching feeling)

This has never happened before and I’m still 8 days away from my expected period.

Could this be implantation bleeding or something else?

(Images in tmi blur below! (Please ignore the previous period stains behind the pink that I couldn’t get out) also I put the pink shorts on after so it’s not pink dye from them coming through as I’ve been wearing black pants all day!)
