TTC Advice

Please can someone give me some advice. Me and my fiancé have been ttc for over a year now and still nothing. Been to doctors and they said to see how I go for a few more cycles.

I want to know what other people did differently the time they got their bfp. Is there any other pregnancy vitamins I can take or ovulation pills I can take other than folic acid?

Please let me know what you guys did differently and how you got pregnant or if you have been ttc as long as me how do you keep going after every negative
