What Can I Do With My Data?

I enjoy keeping track of things about me. For example, I've kept a diary since first year of high school, and have been tracking my weight and diet-related things on app since this summer. Another data I've been tracking for years is my period, since 2011. I got my period today, which was only 20 days since the last time (my average cycle is 35 days), so this got me to think what better method can I use to predict what will happen to my body, based on these data I've been tracking.
