I am getting married and started reading about birth control. I am thinking about using the IUD. Do you have any thoughts on that?
With the older generation of IUDs, I would have considered this among the worst possible options. The newer copper or progesterone – containing IUDs are safer and far less likely to cause infections, perforations of the uterus, and other problems. However, they are thought to work both by interfering with sperm and also by “postfertilization mechanisms,” which means preventing implantation in the uterus of fertilized eggs/zygotes/embryos. That is to say, even the newer IUDs appear to induce early abortions in some cases.
I’d advise looking at other options.
As I stated for another questioner, you might wish to consider looking up Natural Family Planning methods, such as the Billings method (http://www.billingslife.org/).
It was shown in a 1992 British Journal of Medicine article to be cheap, effective, side-effect free, and reliable with a success rate equivalent to combined oral contraceptive pills, even in very poor areas (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1678728).
