3 years of being on birth control

Warning: This is completely based on my own experiences; please do your own research before trying different types of birth control. TL;DR: Sex hormone binding globulin (SHBG), which is anti-correlated with free testosterone, seems to predict how well I tolerate birth control. None of them does everything I want--I just want to be me without the painful periods smh. I started getting painful cramps in high school, but it was mostly manageable as long as I took some Tylenol within eight hours of my period starting. If I forgot, I was mostly fine, just in some pain.
