9 days late..

The last time I ever had a late period in the last 7 years was when I was pregnant, at that time I tested after 3 days of being late and had a vvvfp. I just had my daughter 10 months ago and this is also the first time my period has been late since!! Today makes nine days!! I tested at like 5 or 6 days but it was negative, but the ink seemed to bleed funny I’ll insert the picture, it was weird to me never had a test do that. Anyways should I wait and keep testing or just assume I’m not pregnant???? Thanks for any feedback!
