Weed and Pregnancy

So I was curious if any of you guys may have any idea as to whether or not my baby and I would still test positive for weed if I stop entirely..today. I’m 21 weeks exactly, and not due until late August, maybe even early September.

A lot of people say if I stop by 27 weeks, or in my third trimester, that we will be just fine..I figured why not stop even earlier. I’ll bear with my depression and anxiety somehow. TIA if you have any advice or any help! :)
