On the bar and now suddenly period?

Malissa

Hi ladies, so I have been on the implanox bar for about 5-6 months now. I first got my period about 2 weeks into getting it which is normal and now suddenly today I am getting some irritations and discharge.... a little.. chunky... (terribly sorry for the imagery). My partner and I have been having sex quite regularly, almost every weekend 2 to 3 and some week days times but we always check the condom after making sure it's all good. Now suddenly I am having my period but my doctor has told me that it's only natural to have your period once the bar is close to needing a change and taken out. I also know that the bar I am using is for 3 years, so what gives? I have also taken 2 pregnancy tests about 1 to 2 weeks ago and it was negative. A

ny suggestions ladies or similar stories? really concerned?
