Boy, ya got me there, no mention of IUD in Scripture...
Define "devout".
Your IUD is designed to inflame the uterine lining, thus not a prevention for conceiving, merely an automatic way to reject the newly conceived individual human beings who begin thier bodily existence within your body. Try practicing contraception, as an alternative to 'mordiception' ... otherwise known as abortion. [As a man who chose vasectomy rather than have his precious wife be a killing field for very young individual children 9we got pregnant with a Dalcon Shield insitu), I can recommend that means of contraception ... and tubal ligations are another good means.]
