I had the copper coil in for 9 months. Had pretty much constant bleeding, irregular periods awful mood swings. About 5weeks ago i had really heavy bleeding for a week and have found that my coil has come out. i had a scan to make sure i was out and noting abnormal was found was told to go back to docs to discuss what to try next so i am trying the marina coil. The only thing that is on my mind is i havn't had a period for about 5 weeks now. i've not had sex for 3 months so couldnt be pregnant. if i was they would have seen something in the scan. is it normal for it to take this long for my cycle to continue? I feel like im about to come on (bad back, tired, tumy pains) for about a week and still nothing.
