HI, Implant contraceptive (Minera) releases hormone progesterone, in body for contraception. It causes pelvic congestion, frequency of urination so you may have side effects of the implant. The side effects reduce with time. But I would suggest urine check up to exclude any associated infection (which can exaggerate the symptoms). If present, specific treatment would help you! Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Vasudha Jayant Athavale, General & Family Physician
