3 Days Late Month after IUD Removal

Hi All,

First time poster but this app has been so helpful! I removed my IUD at the beginning of December and about a week or two later got my period which lasted for three days (prior to that I had not gotten my period for two years). I tracked my ovulation and had sex multiple times around my ovulation date. My period was supposed to start three days ago and it has not. I am also getting a negative for HCG. Has anyone else had this issue with IUD removal?

Thank you!
