Prediction (assuming it hasn’t happened already): Some scammer will market a pseudo-science based “pregnancy detector” wand and try to peddle it to anti-abortion police, church vigilantes, bounty hunters, etc.
Back in the early aughts. a completely fake bomb detector sold thousands of units, yielding millions in profit for the scammers. The Iraqi police were one customer and they actually used it at hot checkpoints, with catastrophic results.
