... few hours i was shaking being sick had the worst headache and felt like I was gonna faint thankfully after a few days most of these symptoms disappeared. I am however having to deal with constant cramps in my lower abdomen and back and bleeding heavily on and off. I agreed to have the coil to help my periods but right now ive had enough should I wait it out and see if it settles its making me feel so ill and down i dont know what to do
