What are some ways to improve the case of secondary infertility? TCM? Western? Safe and proven methods please.

I have tried TCM while ttc my 2nd child for about 6months. But no results. I guess sometimes is just a coinsidence or different people reacts differently to the TCM medicines and treatment. I have a friend even tried accupunture to get a baby after no.1 for a year and didn't manage to conceive. So instead of spending money on TCM which the results is not 100% guarantee, go straight to get diagnosed by gynae.
