Contraceptive pill

I’m almost 14 and I get the worst period cramps, not being over dramatic but I’m either sick or I faint during the first 1-2 days.

My mum is a midwife and knows a lot about stuff like this and she thinks I should start taking the pill, however I’ve read/heard off many people it just messes up your body. At the moment this is the best option as I am missing at least 1-2 days of school every month because of the pain.

If anyone has any ideas how I can ease/stop the pain, that would be highly helpful! Xo
