I have been using the implanon now for 10 years getting it changed every 3 years as your ment to. I have always had it removed and replaced the same day. At the end of April I had it renewed and got a new one put in. I had sex 11 days afterwards and the condom broke, I didn't think even think to get the morning after pill, so I missed that opportunity. I'm so paranoid about getting pregnant hence why I've been using the implanon for 10 years now, I never had an issue in the past with unprotected sex. My question is when you get it re-newed is it effective immediately because the drug is still in your system or did the do the right thing waiting 11 days. Just want to know if I'm covered. I know it can mess up your periods as it has in the past and in the last 6 weeks that I've had the new one in my arm I have only had the tiniest bleed that lasted 1 day. Is this also normal I hope you can clear up my concern
