If you've only been TTC for

If you've only been TTC for 5 month's will the doctor put you on anything to help convince or regular you're body ? I have irregular periods and I feel that's the reason why I can't convince especially because I never get a Positive ovulation tests. I'm going to in to see a OBgyn Friday. What are some questions I can ask? Honestly I'm just ready to say. How come my body hasn't convinced yet, what's wrong with my body!?. But I don't want to jump to that and blame myself . Any advice would work thank you
