Feeling sad but okay

We've been trying for 10mo and have not conceived. I feel like I'm timing right, I bought the Ava bracelet 3 mo ago and its hella accurate tracking my cycle, tried preseed this last month. Nothing. We are going to give it another go next month but if we don't conceive I want to get a fertility work up. Can any woman on here tell me what to expect or what to ask the doctor?????
