To some people, a period is simply an annoyance. And it is annoying, but since being diagnosed with pcos and dealing with irregular cycles most of my post-pubescent life, I appreciate it. For nearly 10 years, I had to rely on birth control to regulate my cycles. Without it, I'd go 6+ months without a period. Super unhealthy. When I began focusing on my health, they started to regulate. Since November 2016, I've only missed two cycles, which was during the summer last year. And since this March, it's come like clockwork. The 18th of every month I've gotten it. It's become predictable. I can even recognize when I'm pmsing. I wasn't able to do that before. I'm pretty certain I can pinpoint ovulation symptoms. It's interesting, and really goes to show how important a healthy lifestyle is when it comes to managing pcos.
