Thanks for your query.
If the urination is foul smelling, it sounds like a urinary tract infection
Also, the fact that she urinates only twice a day is not normal.
SHe needs to increase her fluid intake and consult a gynecologist to rule out urinary infecion.
ALso, on implanon
, it is very common to have mild spotting off and on.
It is a common side effect.
The implanon would definitely protect you against pregnancy
, however no method is foolproof as you know.
SO, while she consults the doctor for the urinary problem, she should also ensure that there is no incidental pregnancy.
