I got nexplanon put in my arm in November of 2018. I bled all the time. I stopped having my periods about 2 in a half months ago. Now, I’m having very creamy brown discharge. I feel like it’s way too late for that to be “old blood” I’m having horrible stomachs cramps and headaches. The cramps have been lasting for a week now. I feel like throwing up all the time with constant headaches and I don’t feel like doing anything anymore. What is it?
