Police in the United Kingdom are using data from period tracking apps and mass spectrometry tests conducted on blood, placenta, and urine to investigate patients who have had “unexplained” miscarriages.
Though abortion is legal in the UK, there are TRAP laws in place requiring certain conditions to be met first, paramount of which is that two separate doctors need to agree that the patient meets the criteria of the 1967 Abortion Act before any treatment can go ahead. Self-managed abortion is a criminal offense with a maximum sentence of life imprisonment in the UK, as is any abortion performed after the pregnancy has progressed passed 23 weeks and six days, unless the patient is at risk of serious physical harm or death, or the fetus has severe developmental anomalies.
They talk about this as if it's mysterious. Not actually the fact that the working world is still based on one parent works and the other stays at home (offering their life in sacrifice to the system and providing the next generation for free, but I digress) but both parents HAVE to work to survive because the cost of living is through the roof. Child care costs too much, almost entirely wiping out one parents wage. And they could choose to offer incentives or address the reasons for the low birth rate, they know the reasons. But no, fear, criminalisation, those work better, as tools, to keep the chattel in line.
