What is your birth control experience?

So I have been on the pill for the past 5 years. Before I started birth control I used to have to stay home from school because I would have terrible cramps, nausea, and migraines. My period was heavy and would last for 5 days. For the first year of being on the pill all of the symptoms stayed the same. After the first year everything became less and less. I would have a mild period and it lasted about 4-5days.
