I had my copper iud removed January 6 ,2017 & my period was due January 12, 2017, it's now January 19th Seven days late. This is extremely unusual for me bcuz I am never been late even while the iud was still in.... Me & My husband had sex two days prior to having the iud removed. But after that we hadn't had sex until yesterday. So I'm very confused as to what's going on or why.... Is This Normal ???
