TCM during Pregnancy

I have been consuming tcm meds daily for 3 months when trying to conceive and i found out i was pregnant, at 4W6D today. Went back to my TCM and she prescribed tcm meds (for my constipation & 安胎药) for a week and was told to return next week. Wanted to ask other mummies here, should I continue with the TCM or stop soon? Not sure if it's safe but my practitioner seems experienced. I'm just worried and maybe paranoid. The meds she gave me are solutions made from powder so I'm not sure what herbs were used too.
