Which Chinese traditional medicine would you not recommend I take if I am trying to conceive?

Many many many. But the best is to see a TCM practitioner to have your body assessed because it is about holistic approach and to help support the body to conceive. Then you can have a better understanding of your own body's needs to help you try to conceive. In fact, if you are trying to conceive and is considering TCM, pls DO NOT self medicate - because everybody's body needs are different and different kinds of medicine are needed/need to be avoided in the different phases of the menstrual cycle.
