Etonogestrel
"Had Nexplanon implanted in my arm September of 2015. After 2nd month I began to have irregular periods. Starting January 14th 2016 I have been bleeding ever since (2mo straight) with maybe half a day of relief. I've had cramps, headaches & been more tired than usual. Now 6months on nexplanon & am experiencing pains to the right & left of my bellybutton area. Called Obgyn & she recommended take 800mg ibuprofen to ease cramps & decrease flow (since it is heavier than normal period). The blood is dark, sometimes" rust " colored or dark brown. Now Dr.says to have ultrasound done."
