I was on the mirana implant for almost a year and had it taken out. Once it was out I waited on my period and once my period had come and gone I put in the nuvaring. My husband and I had sex 4 days after I started the nuvaring. Before sex we took the nuvaring out and put it back in a little over three hours later. Also on that day I ha thick white discharge. Could I be pregnant because I hadn't had the nuvaring in long?
