I've had a copper iud put on after an abortion in mid october. i got my period on 12th november, that one was very heavy and lasted for about 8 days, i am usually on a 28 day cycle previously. It's already 18th december, which is more than 30 days after my last period and i dont think i have my full period yet, as i only had a bit of bleeding occured on 16th, slightly more on 17th and still very light today. I haven't had sex since 10th November, which is 2 days before having my last period. should i go see a doctor, and if not, when should i consider seeing one? what could be wrong, if anything, with me? i dont feel nausea/vomiting.
