Needs some advice

I am 19 years old I have been trying to conceive since January of 2018. My periods have been here and there or not at all for a while year. Recently my periods has come back on its own but I’ve been testing 2 times a day to see if I’m ovulating and I just seems like I’m not. What do I tell my doctors or ask? I kinda feel like I’m going to be judge. I don’t drink or smoke I’m very mature for my age. My boyfriend ( who I call hubby) we have been together for almost 5 years is almost 24. Any advice how to go about asking my doctor please! I have really bad anxiety and have medication I take.
