Hello there.
Implanon is a hormonal device.
Side effects of implanon use include lighter, irregular and infrequent bleeding.
Sometimes there are no periods at all which is not accountable to
pregnancy if the device was used in the right way.
So your pink discharge can be due to the side effect of implanon.
Nausea, headache, sore breasts and weight gain are also seen with implanon use.
Smoking does not affects the
contraceptive efficacy of implanon but it does predispose you to serious side effects associated with implanon like stroke and
blood clots.
So it is better if you stop smoking with implanon in situ.
You can test for pregnancy just to be sure.
Secondly I want you to visit your gynecologist for an internal examination so as to rule out other causes of unexpected vaginal bleeding (pink discharge).
A
Pap smear is also mandatory if you have not done in the past one year.
TAKE CARE.
