My friend had the same scare and her gynae told her that at such early stage, one-off accidental intake usually shouldn't cause major harm, so try not to stress yourself out! That said, someone here did mention that 十全大补汤 is quite heaty, better to avoid all those strong herbal soups when pregnant, especially in the first trimester. My neighbour also shared that her TCM physician actually advised her to hold off all tonics until after the first trimester at least.
