So I'm on month 4 with a copper coil. My period have been intense and painful and heavy but this month I'm slightly worried. Not only is it late but I've been super nauseous, getting hot flashes, constant urge to go for a wee and insomnia. Now part of me is trying to convince myself this is just intense PMS but then today I've noticed my nipples are really sensitive (like they where when I was pregnant with twins). I can't afford a pregnancy test till Tuesday so I know I just have to wait but has anyone got pregnant on the coil? Is it dangerous?
