My son is 5 months old and I had nexplanon put in for birth control about 2.5 weeks ago. Since then I have been very easily upset and cry very easily. I also have had other weird things like horrible back ache and shoulder ache and I constantly worry that something is wrong with me. I am also exhausted all the time, I feel like I could sleep all day everyday and still be tired. I am going to my regular doctor on Wednesday but I am wondering if these are normal symptoms from nexplanon or what others experiences have been with it. I hate to give up and get it removed already but the crying all the time and worrying so much is tiresome.
