PCOS anyone relate?

Hannah
I have pcos I am sure many women do. I have tried for 4 years to get pregnant. I will go months with bleeding then months with no period. It's so hard. Dr wants me on birth control and that defeats me trying to have a baby. I am about ready to give up. Has anyone else had this problem. Any success or tricks to know when your ovulation time is when your cycle is wacky?
