Anyone know how many doses of regular strength Tylenol tablets a pregnant woman can take in one day? I have a horrible headache that started about 24 hours ago. I took two Tylenol around 4pm yesterday and two more at 10pm. I haven't taken any more yet. The label says "do not exceed 12 tablets in a 24 hour period", but I don't know if this rule applies for pregnant woman...I would think it's probably less. Thoughts?
