Salam! Implantation bleeding can be tricky to figure out lah, mine was super light, like brown spotting for a day or two, totally different from my normal period flow. A few of us mummies noticed it happened around 6-12 days after ovulation, but honestly the safest way to know for sure is just to do a pregnancy test after a few days or check with your doctor, especially if you're unsure whether it's implantation or something else. Wishing you all the best!
