What should I do??

Me and my husband got married last December and we never used any protection during sex cuz both of us wants kids, the laste six months we have TTC# 1 for both of us. But no luck, this week i was doing some research and I found a good reviews about Vitex and Fertility blend because my cycles are irregular(2-3months sometimes longer than that). I don't know what to do should I give Vitex or fertility blend a try or go see the gyno first please any advise.
