I have had the implanon for 3 years now. It s scheduled to come out this month. I understand that you can have pregnancy symptoms while on the implanon but I have had a regular menstrual for the past year but I haven t had one since the first of May this year. I have also experienced nausea, heart burn (which I haven t had since I was pregnant with my son 6 years ago,) and some lower abdominal pain over the last month. I took 2 home pregnancy tests a couple of weeks ago that showed negative. I was just wondering if the implanon could cause a false negative or if this is all in my head.
