False positive pregnancy tests

[HelsBels2]

I have to ask if it is possible to have a false positive pregnancy test. I have the implant (implanon) which I was told is 100% effective by the doctor. Also I had a period end of December. I did 2 pregnancy test on monday, one of which was definitely negative, the other had a very faint line. What does this mean? Pls can anyone help?

Good luck whatever the outcome!

Thanks. That would explain it, so basically the answer is yes, it is possible. Thanks again.

Can i just say, the only form of contraception that is 100% gauranteed is sterilisation or the snip. All other forms of long term contraception, coil, implant etc are around 98/99% effective.
So if you are still concerned in a couple of weeks, i would do another just in case.
good luck :-)
