Nexplanon periods?!

Soooo I got the Nexplanon implant recently. I just got my first period since having it 5 days late which isn’t shocking I’m fine with being irregular. BUT THE CRAMPS?! I’ve always had pretty bad cramps but this?! THIS?! No ma’am. No can do. The pain?! Unbearable. Stomach, back, and butthole pain AT ONCE. The worst. Does it go away with time??? Will I be like this for 3 years?!
