Breastfeeding and ttc, positive hpt with breastmilk?

So I know this is going to sound weird.... I'm not a first time mom, but this is the first time I've read or tried this.

I read tonight that if you're breastfeeding, and ttc, and you do get pregnant, that it can take longer for hcg to show up on a hpt urine test, but that you can express some breast milk on a hpt and it can be accurate.... well, I had a maybe very faint test this afternoon, not fmu.... and out of sheer curiosity I tried one with some breast milk tonight.... and I got a darker positive!!! Not getting too excited, but was wondering what you all thought...

The logic behind it is, that your urine is the last place the hcg ends up bc it's the excess being excreted out... so it shows up in your blood first... and like alcohol, can show up in your breast milk too.... my little guy who loved to breasfeed, self weaned about 4 days ago :(

Anyways.... just an experiment, sorry so long... top pic is urine, bottom is breast milk, both pics taken at 3 min.
