Confused

Chasity

So I’ve been trying to conceive for five months now. I am five days late. This morning I had some brown/pinkish discharge and it wasn’t heavy at all. Lasted half of the day, even when I would wipe it was LIGHT. Now when I wipe I don’t see no discharge, looks normal to me. Mild cramps, and lower back ache. Other then that I’m fine. Confused if that was implantation bleeding or not.
