But taking a few early in pregnancy shouldn't
be a problem, although it isn't recommended. Most people take
SOMETHING over the counter before they know they are pregnant.
Tylenol is fine, by the way. Just don't overdo ANY medicine. Your doc will give you a list of "safe" meds to take in pregnancy.
As for the spotting, of course mention that. If it becomes bright red, increases in amount, or is accompanied by abd. pain, call your doc right away.
