Put the whip down! B6 is a water soluble vitamin and excess amounts are normally excreted (assuming you have normal kidney function). Also, during most ofthe timeframe you descrive (I'm assuming by "2 weeks pregnant" you mean you are 2 weeks after ovulation and may or may not have had a positive pregnancy test yet), the fertilized egg hadn't even implanted yet -- therefore it wasn;t exposed to the B6 for more tahn a few days.

You and your baby (if you are even pregnant!) should be just fine, but neitehr one of you needs that much B6.
