f#&*%king 3 min rule!
i.e women with healthy placenta lose desire for coffee whereas the others still have the desire and (presumably) consume more coffee. Its not the coffee that causes the increase in miscarriages.
When my wife was pregnant (with healthy baby) she could not come within 1000 ft of a Starbucks w/o turnig green puking.
Note:I know a sample size of 1 is statistcally insignificant.
