Switching Birth Controls

Brooke
Hi ladies ! So I've been on the pill for almost a year now and I'm thinking into changing to the shot but I'm kinda nervous! Has anyone made the switch? Is it effective? The pill is very effective for me but it makes my periods last 2 weeks or more and I get them every two weeks and I'm tired of it 😕 So please help me with info if you can! Thank you all 😊
