TTC for over nine months

My husband and I have been trying to conceive since our one year anniversary. That was a little over nine months ago. Should we make an appointment to talk to a doctor or should we try for a little longer? I haven’t been on any form of BC for the past nine months but before that I had the nexplanon implant for two years and the implanon implant before that for three years. Could that be a reason we haven’t had any success?
