Hi and thank you so much for this query. I a sorry to hear about the pains and discharge you are experiencing. I am also very happy to know you are taking active measures to prevent any pregnancies at this time. Having unprotected sex is a risk factor for STDs. Some of the stay for a while without symptoms and only become symptomatic later on. THis might be the case with you. Also, the fact that you have a coil inserted increases the chances of a Pelvic infection. Any pains or discharge in a woman with a coil warrants a thorough investigation because it could be related to this coil. It is difficult to tell in your case whether this is caused by a longtime silent infection or the coil you recently got. You will need a complete clinical evaluation and testing to tell what the exact cause is. Also, bear in mind that not all genital infections in a female are caused caused by a sexually transmitted germ. others like gardnerella vaginalis are not transmitted sexually. so please, meet with you OBGYN and get this sorted out. Please, remember that the coil only prevents against pregnancy and not an infection. You should always consider using a protection to be on a safer side. I hope i have answered your query fully. Please, feel free to return and request for more information if you so desire. I wish you all the best as you get this problem addressed and your health restored. Thank you for using our services.
