Ok I have been on Implanon since January 26, 2014. I started coughing a lot during the 1st week of February - it progressed to wheezing. I went to my Doctor 2x and he couldn't figure out what was going on. He sent me to the ENT. He couldn't find anything. Went to my allergist and found that I have asthma. I have never had asthma before. Has anyone else had this type of reaction after having the Implanon inserted?
