Always Irregular!

My husband and I have been TTC for 6 months. I haven't stressed much about it, assuming it'll happen when it happens.. but the frustrating part is that my cycles are so irregular.. running everywhere from 27 days to 35, or even 56!!! Who can work with this?! It wasn't until this cycle that I started feeling down and truly upset about it.. not sure how to regulate. He and I are both healthy, eat vegan/vegetarian and juice all the time.. (the pineapple has been a plenty!!) We're 28, nearing 29.. & just ready to get started on our family already!
