Multivits/TCM physician to see?

Dear all, I just had a miscarriage at 9 weeks. Everything was going well and just one day, realized there's spotting, went into A&E, baby heartbeat can't be detected though baby was growing well - doubled in size from last scan. As we are hoping for rainbow baby now, we are wondering if there's anything else we could have done better for the next pregnancy. For the last, the Dr only gave folic acid, so I was only taking that and maternal milk powder. Just wondering if there's any multivitamins or even good TCM physician recommendation that I should go and consult? Thank you for your kind sharing in advance!
