Mini-Pill Thoughts?

Holly • F/16/UK Just your average, run of the mill, teenage feminist hiding in the shell of a sad British student.
I'm 16 and I've been prescribed the Mini-Pill this week to aid with my excruciatingly painful, long periods. I've been reading a lot about it recently and I don't start them until my next period, in April. Any thoughts/ problems/ positives?
