getting off the pill


hi ladies. I've been on birth control pills for 12 years, but my husband and I have decided to go off it. I'm hoping for some positive side effects like maybe my sex drive will improve. but I'm also really worried about some negatives. I used to have really heavy, frequent, long, and unpredictable periods with horrible cramps, back pain, and fatigue. I know I was young and I'm hoping maybe my periods will be different now. has anyone been through this?
