Implementation bleeding?

Hello ladies! I'll keep it short and sweet. I have a 9 month old I'm breastfeeding and havent gotten my cycle back yet. I noticed this evening the tissue I wiped with was light pink, like hubba bubba gum pink. After that nothing since and I'm not cramping or anything. I've never had normal cycles just been on the lookout for signs of ovulation but got none. First, does this sound like possible implantation bleeding? And second, would testing tomorrow be too soon?

Thank you!!😊
