Birth control advice

Bri • Wife • Mama to Markell 🩵 • fur mama ♥️
I've been on the pill for 3 years and it will work for a couple months the I get bad headaches and I get nauseous. The pill was origanlly used to treat  severe cramps and now the cramps have came back and it seems like the pill is killing me. I've been trying to get until my gyno for 3months for these issues. I finally switched doctors because she canceled on me 3 times. Any way I go in a couple weeks and I'm thinking about getting a different type of birth control. I was thinking maybe the shot or implant. Can I have some opinions. I'm sexually active and going without isn't an option
