So I have the nexplanon implant and I've had this period for 10/11 days. Bleeding for this long is normal for me but I think its ending because its brown instead of red blood. All week I've hardly had an appetite and still don't. My stomach is hungry but everytime I go to eat it's not good or makes me gag and full fast. I also had diarrhea once this morning. I don't even want to get off the couch either. Is this normal? I'm freaking out.
