Menstration Issues

Hey all!

I've always had irregular periods. Starting when I was 13, they would only ever come every 2, 3, or 4 months. One time I went 6 months without having one. When I was 16, I went on birth control for about a year, during which time they were regular. But as soon as I went off the pill, they were irregular again. I was diagnosed with PCOS. However, I serious question the validity of this diagnosis.

About a year ago I started following 80/10/10. Granted, I haven't followed it 100%. Some weeks I'll follow it 100%. Other weeks it's more like 60%. Especially during the winter, I found myself eating spicy rice/curry dishes. Overall though, for the past year my diet has consisted primarily of raw fruits and vegetables.

And I'm happy to say, that for the first time in my life my period is coming once a month. It's on a 30ish day cycle. This is extremely exciting. I think that the increase in nutrition (from all the fruits and veggies) along with the eliminate of foods with hormones (milk and meat), allowed my body to rebalance itself.

But here's the problem:

Even though my periods are finally regular, they are extremely painful. Like, vomiting, cold sweats, unable to stand up painful. It's usually only bad on the first day, but it is so bad that all I can do is roll around in pain for 6 hours. I literally can not even stand up. This last time I even blacked out, and when my vision finally returned, there were white sparkles all over the place.

So... my question is this:

Have any other ladies had problems like this?

Do you think it is part of the cleansing/detox process?

I have never been overweight, but I did eat meat and dairy pretty much everyday for the first 18 years of my life.  I'm wondering if the toxins from these foods have been stored in my tissues, and then are violently released during menstration? Just an idea.

I am thrilled to finally have regular periods, but it's frusterating that they are so debilitating.
