Hormones out of wack!

Hello! I’m 33 and soon to be 34 yrs old and for the passed few years my s/o and I have been trying for baby #2. And still not pregnant. I’ve been tracking and still nothing. But these several months I’ve noticed my cycles has been coming much later. About almost 3 weeks late. I’ve stated this to my ob and she prescribed me Provera to restart my cycle. She’s stating that my hormones could be the cause of me not getting pregnant. Has anyone ever taken Provera and did it help any? And what can I take to get my hormones back in order?
