Hormone imbalanced

So I've been ttc and no luck. Lately my periods and pms have gotten really weird. My periods have become shorter and lighter and my pms is horrible! My boobs starts hurting way more than usual, I get nauseous, my back pain is unbearable! I stay in the bed most days the week before and during period week. It's a real interference in my daily life. What should I do? Is it maybe anyway to balance out my hormones besides birth control?
