Birth control: the copper iud vs the implant?

Okay ladies, so I’ve taken the pill before and I didn’t like it. It’s a hassle to remember to take it and it also made me gain weight ( which is really ironic because I’m skinny and never gain weight but I would’ve loved it if I had gain weight somewhere else rather than my face :( lol) anyways let me know what was your experiences bad, good? Any side effects? Thank you ladies 😊
