Really need some advice

evening girls you will have to excuse my lack of knowledge on what all the "dpo"" etc meanings but I need some help. I'm 20 and my partner 25 we have been trying since January and nothing. I have been off contraception for nearly a year now and am starting to get concerned as have always thought it was so easy to get pregnant and so many people have unexpected ones my age. should I be thinking about a doctors appointment?
