"nexplanon is definitely effective in the sense that i can&#039;t have sex anymore. i got it early november 2014, bled daily till december then was absolutely fine... no spotting or anything.  up until late july where i have bled  non stop pretty much every day. sometimes a light bleed, and sometimes heavy. due to this i am unable to even attempt sex, which is getting me pretty down. gonna give it another few weeks and go to my gp. if nothing changes i will be going back to condoms as the pill wasn&#039;t my thing."
