birth control
"I have been on nexplanon for little over 3 years. When I first had it inserted, I didn't have my period for 2 months. By the 3rd month I have very faint spotted bleeding. I did get a big nauseated, and had headaches. By the 4th month  I had a really heavy flow that lasted 2 weeks straight after the two weeks it lightened up over 3 days to nothing. From there I was fine, no cramps, no bleeding for 3 months. By then, it would be marked as my 7th month since the implant. I bled for a solid 12 days. And they felt like the worst cramps ever. I literally just stayed in bed for the first 7 days and as 3 weeks before bleeding,  I experienced period cramps. Since then my period was consistent. It came every 3 months and last a little over a week."
