Will there be thc ....

* I'm not asking for judgement I already feel bad*

Will there be thc in my breast milk (exclusively pumping) if I only took 3 hits from a blunt (ONLY three) I won't be doing it again, I instantly got worried that the thc will be passed to her, I'm One week pp and just wanted something to ease my pain & instead made me worried sick. I haven't smoked my whole pregnancy at all and did last night. Anyone have any experience with this.

Also, don't worry I showered & she was in good hands.
