I am on the contraceptive implant and I have been using it for almost 4 years, my most recent one was fitted in august of this year, I was away abroad for the first three months it was fitted and had no problems whatsoever from it, however now I am back in England I have noticed that every time I consume alcohol I get my period the next day. I did not drink alcohol during my time away as it is prohibited in Bangladesh, so I can't tell if this would have happened all along or is a recent development. I do not get my period when I am using the implant usually and the only correlation I can find is that it comes when I have been drinking alcohol the night before, I don't drink often so it has been easy to monitor and in the last 6 weeks it has happened 3 times.
