"had implanon inserted in august 2009. bled for over 2 months into novemeber and have not had a period since. in the past week have experienced breast tenderness, nausea, lower back pain and slight dizziness which i worried was due to pregnancy. have done 3 negative tests, however i feel slightly paranoid still and could swear i have a strange taste in my mouth normally associated with pregnancy but i hope it&#039;s just all in my head! going to the doctors on thursday so here&#039;s hoping i&#039;m not caught out in that tenth of a percent!"
