Does Taking Alcohol Has Any Effect On Implanon?

I have the implanon in, and have had it for over a year now, I am having continuous symptoms of being pregnant exactly like I had with my other two children, whom of which i fell pregnant with whilst being on the pill.. So im now becomming scared that the implanon has not worked for me either .. why could this have happened? does alcohol affect the implanon or any other things?! im planning to take a HPT soon
