Normal periods with Paragard an now 5days late

Just wondering if anyone else has had this issue. I had the Paragard for three years. I had it removed on March 17 while on my period unfountley. My periods have been normal where normal on the IUD, typical 7days for me. Since I have had it removed. I have not started my period. I was suppose to start April 10th an still nothing. Also I took a pregnancy test on the 12th an came out negative. I have had every symptom of pregnancy all the way to metellic taste in my mouth,but I just brushed it off an thought it could be the side affect to my prenatal vitamins. My husband& I are trying to conceive. Has anyone else had this issue?
