I need some form of contraception that is hormone free. I've tried all types of pill and none agree with me. 
I have PCOS so I'm guessing my hormones are so far from normal that the balance of hormone in the pill isn't right when added to mine iyswim.
Anyhow it looks like I'm left with condoms, the copper coil or sterilisation.
Condoms don't work well for me and dh so they're out.
Sterilisation is very final - which is fine by me. I DO NOT want any more dc. But I'm guessing I won't get on the Nhs until I've tried everything else.
Which leaves me with the copper coil.
I'm a bit worried about the heavier, more painful periods bit. Currently my periods aren't too heavy (only need a day at most of super tampon), but drag on for 8 days (in a 35+ day cycle). They're also painful - but taking feminax regularly helps with that
Would the copper coil be a bad idea given my current periods? 
I've got ages to wait as at our drs only the nurse will prescribe contraception (!) and it's a 5 week wait to see her!!!
