"so i got the implant on april 15 and immediately i started feeling mood swings , one moment i felt happy the next mad . constantly getting mad at my boyfriend for little things that didn&#039;t matter . felt irritated all the time . my period was late . i started on may 6th it is may 12th now and still on my period . i eat a lot now . gained a couple pounds . got some acne . sometimes i feel depressed . considering getting it removed but 99% chance of not getting pregnant is what&#039;s keeping me to stay with the birth control ."
