TTC for over a year. Aged 32

After TTC for over a year, my Gyno has checked myself and partner several times and says everything is healthy, i have regular periods etc. And she said that us usually you should be pregnant by now.

She said there is another procedure where they put a camera inside to see inside my tubes if there is an infection ir something but it is very painful? Or wait and keep trying a while longer. I'm 32 and nit sure what to do.? Are we not having sex enough or on the correct days confused...
