Weird periods after pill.?

I've been off the pill for TWO YEARS and my periods haven't been normal since. It is frustrating. Incredibly aggrivating. And depressing. I wish I wouldn't have been so concerned with NOT getting pregnant. I never knew it would be so hard. I've been trying for 14 months. Sometimes I skip my period, and my last cycle was 49 days. Ugh... I wish I would've just left my body alone! And never messed with my hormones, because I can't seem to get back to normal.
