I had the copper coil fitted yesterday. The doctor didn't show me how to feel for the strings but I know you're supposed to. I've tried to feel so I can get an idea of what I'm supposed to be feeling for but I can feel my cervix but no strings. Is it likely that my cervix is swollen from having it fitted (it feels swollen) and that's why I can't feel the strings? Should I just assume it's fine? My boyfriend is coming over tomorrow and if all feels okay I don't know if it's okay to have sex without other protection. Any ideas?
