Pregnant?

Watery bleeding which was light compared to normal period bleed (no cramps or anything like that) 6 weeks after last period. Only really lasted 2 days then turned to just pink Cm, not heavy or thick enough for tampon. I put it down to period just being late. But I’m now wondering if I am in fact pregnant? Ive read some articles and legs online that watery bleeding with no cramps can happened around 6/7 week mark due to placenta burrowing into uterine wall. I know it could just be my period being late and I know sometimes they can be different. But it seems funny that it’s happened around the right time! Has anyone experienced this?
