Posting here for traffic as I posted in Women's Health and didn't get any responses.
I had the copper coil put in 8 months ago. For the first month I had some spotting but no spotting since. My periods have been longer and heavier but more or less the same each month. Until this month, when I had one day of spotting, then nothing for 2 days, then 3 days of spotting, a period for 10 days - 3 of which were very heavy - and since then (over a week ago) I've had spotting and cramping on and off. Since yesterday the cramping has been constant but the spotting hasn't. I checked the strings of the coil last night and felt a bump on my cervix. I've also felt very fatigued for the past 3 weeks - more than the usual tiredness from having 2 children.
I'm going to try to get an appointment with the GP this morning and I know that's the only way I can get actual answers, but I'm really worried about what's going on and would like to hear if anyone has had something similar and it's all been fine.
