Correct. Right now, "minds and hearts" are governed by sympathy for the pregnant women -- this baby will cause them a lot of stress and inconvenience, which we can all understand.
The only counter to this is to re-establish the understanding of what the "choice" is really all about --that "reason X" is sufficient to justify the death of the unborn child.
The task is to establish that second part in peoples' minds -- that we're talking about reasons to decide to kill a child. This technology might do it -- but not on its own.
