IUD help

I've been on the implant for two years now & at first I loved it I barely got a period but 6 months ago I had a 2 month period so I went to my Gyno & she gave me birth control pills to regulate it. I've been on the pills for 2 months now & they make me so nasueas so I stopped taking them & immediately after I started my period 10 days before I'm supposed to. im making an appointment to get my implant out because it's not helping regulate my period anymore & talk to my gyno about other options. My friend told about considering an IUD but I'm scared it will affect me like the implant. What are your guy's expirences with them? I just want to see how it affects other people so when I talk to my gyno I may consider it
