First off...CONGRATULATIONS!!! I am a bit confused as to why you say you are 8 weeks along. I'm guessing since the pregnancy has not been confirmed by a Dr. yet, that you are basing it on you last period. Luckily for you, in this case, that is not necessarily a very accurate way to date a pregnancy. So there is a decent chance that you are not as far along as you may think. However, even if you are 8 weeks pregnant, the baby is very well protected and should suffer no ill effect from the drugs taken earier in the pregnancy. As someone else mentioned the best advice at this point is try not to stress, take prenatal vitamins and eat healthy diet.
