Aisham, your issue sounds very similar to mine. I've had the copper IUD since March. Finally around June, it began to regulate itself (bleeding-wise). My period is actually longer and was very heavy, but have leveled off. This month; however, it was 5 days late, but normal (IUD normal). Three days after my period (I guess this is ovulation period when you feel mild cramps and pain on either side. Actually I've felt it on both this time. I usually have a clear discharge at this time also; but it's spotted with blood and a lot of it. It's been going on for four days now... I wasn't sure if I should get a pregnancy test or just wait it out.
this happens to me and i have the copper IUD for 4 and a half years, i spot lightly and its also when i ovulate with cramps. so im guessing is the iud. oh and also weight gain........... ***** i wanted out.
