Lamictal & Contraception

Hi Gals, I'd love to hear some feedback on contraceptives you have used successfully while taking Lamictal ie IUDs etc.I read so many different things about oral conceptives interacting with the levels.I have been taking Lamictal for over 5 years,I'm sick of my heavy periods and poor hubby having to always use condoms.Any advice,stories of medications/IUDs you have used would be great! Cheers gals :) :)
