I havent had a period in a few years and i recently got my coil out say 6weeks ago and been having unprotected sex

And i had some spotting on the 17th for about 3days and then on the 22nov i had white sticky discharge? I dont know whats it is i cant keep tabs on my period as im not sure if the 17th was my period?
