How to find research conferences to attend?

Hi. I’m a PhD student of Stanford university having epidemiological and behavioral studies as my research area. I need to present my research paper in any conference within the two months. But I don’t know where and how would I find the information about the upcoming conferences and proceedings at various institutes? I keep on searching for it online but only get the handful of those and that too turns out to be fake. Tell me please what should I do?
