Hi, I had a copper coil fitted about 6 weeks ago. Everything ok and had my first period after fitting without too much trouble. Now onto my second period which arrived a week early and have now been bleeding heavily for 7 days. No real pain, although I keep getting a dull ache in my right side. Is this usual? Beginning to feel like I can't function properly - really tired, irritable, etc. Has this happened to anyone else?
