Walking 12 miles is not only uncomfortable, it is also higher risk to Mom and baby than driving.
You have to balance all the risks and benefits.
Fever during pregnancy can cause neural tube defects, congenital heart defects, orofacial clefts, miscarriage.
It's great that you care so much about the infinitesimal risks of acetaminophen. You should care 100x more about these risks that are 100x or 1000x greater.
It very much is still your wife's body - what other sentient entity is available for consultation?
I also am not sure if she is seeking professional medical advice - 'baby aspirin' is not a blood pressure medication, full stop. If this is based on non-medical doctor advice, please do consult a fully-qualified obstetrician.
Edit, just because this is very worrying to me, for later viewers, aspirin is an NSAID and its use should be weighed similar to that of other NSAIDs in the context of pregnancy. Consider this web page:
https://www.fda.gov/safety/medical-product-safety-informatio...
The baby aspirin is not for hypertension (it does nothing for hypertension). Its goal is to prevent changes in placental vasculature that may lead to severe pre-eclampsia in those already at risk for pre-eclampsia. One clinical sign that demonstrates risk for pre-eclampsia is high blood pressure.
Surely you don't mean what you imply there? Not being sentient or available for consultation don't justify harming a person. A mother absolutely has a moral responsibility not to cause lifelong harm to the sentient entity her baby will later become. You wouldn't say excess alcohol consumption during pregnancy is only up to the mother's decision about her own body when there are adults walking around with terrible lives because of fetal alcohol syndrome.
That's absolutely the case, though, isn't it? I wasn't aware of any laws that bar pregnant women from buying or consuming alcohol. So it's totally up to them.
I would - because the alternative means we are locking up current human beings to act as incubators for potential, future humans
