TTC help

So I've been TTC for quite some time now with little to no success last may I started taking BC due to irregular periods for two years I started dating my bf in June and we moved in together really soon and now we want to have a baby but it's been really hard I stopped taking BC in October and we've been trying since then with absolutely no luck my periods are now regular since stopping the BC and I'm still not pregnant I've spoken to my regular Obgyn and she hasn't really been help either she hasn't run any tests or anything so should I be worried? Should I switch obgyns? or should I see a specialist?
