light negative test but visible can I breastfeed?

I've been taking home tests and I'm negative. can I breastfeed or do I still have thc in my milk and body? this is my most recent test. the other drugs I don't use I just wanted to prove to my mother I wasn't using anymore so she purchased these. I'm 22 but we have CPS on our ass and she wants to prove to them I'm not using.

my others have been darker and regardless of being clean it came out light 😞
