Hi. I am 19 years old. I am on the birth control Implanon for almost three years. I have to get it removed on April 22nd. These past 2 weeks I have been experiencing nausea almost all day, high tend smell, sore breasts(that have become bigger), bloating , constantly having to urinate, constipation, fatigue . I have taken two pregnancy tests about 4 days ago both turned up negative.
