Hi, i have a copper iud for about 3 years now and no problems, until yesterday, when i felt that my cervix dropped and were open a lettle, so i left it, when i went to the bathroom again i felt the string and half of the devise. There was a little bit of bleeding and cramping but went away after a while. so this morning i felt a little bit shaky and it feels like my heart rates a bit up. does this got anything to do with it. Should i be worried? What must i do?
