TTC hoping for the best!!

I've been trying to concieve for 4 years now but its difficult with irregular periods and cystic overies ...... and everytime i get comfortable enough to where we are talking about have kids and trying its like my body says no... I am getting married in June and we are really looking to have a baby because hes affraid if he dont get one now his time clock will run out... i tell him no but hes a man he dont listen.... I know we are 11 years apart and ppl think I'm crazy but i truly want this life with him and having a baby with him would be my lifes miracle... Any Advice from anyone???????
