Implantation bleeding???

So I’m a normal check my cervix person. Well last night at some point I checked my cervix and there was pinkish/brown blood very very light. It’s been almost 5-6 hours and has not gotten heavier at all. It’s only when i check my cervix. Doesn’t come out when I wipe and hasn’t made it on to my pad either. Could this be implantation bleeding or my period?
