TTC is this stuff useful?

Been TTC (trying to conceive) for a while now and it isn’t exactly working but I have gotten pregnant before so I shouldn’t suddenly be infertile? But anyways so now I bought Saw Palmetto, Phytoestrogen cream from Whole Foods and fenugreek and I’m taking Vitamin D & starting on the Emergen-C packs for all the B vitamins and vitamin C. So wondering if that would possibly help? Or am I taking too much? I’m getting my s.o to take the emergen-c packs as well now, especially since he’s currently sick with a stomach bug. Thoughts?
