Help!

Looking for a little advice, live in the uk and been ttc for over a year, I'm now 33 have regular af they always show on time, use clear blue digital dual hormone indicator and they always give me a high for a few days then a peak at the right time...I'm stuck I don't know what else to do?  I've had blood tests done and they came back ok and I have an app with a gynecologist in January.  Anybody have any tips or advice?? Thanks!
