i had A/C when we were ttc DS. once i was PG i went back for another session & the A/C said that at that stage she would do general relaxing A/C & one needle to help try & prevent m/c (well, i'm pretty sure she said something about making sure baby was secure) & not prescribe any TCM - i think she said that they like to leave things as they are & let the body do its job - unless i'd had a history of m/c in which case i'm pretty sure she said she could do some a/c or prescribe some TCM to help.

my memory is a little vague about it now but i'd say it would be worth talking to someone at the very least - could you try posting in the ask an expert section & see if chris tang has any advice/suggestions?
