Oh well, I guess that's why we all have to make our own decisions based on what we feel led to do! If it was that big of a problem (women constantly getting pg with the iud in) they wouldn't be on the market ma'am!!!!
That's why they took them off the market back in the 80's, cuz of the many problems people were having with them. But, obviously they fixed it & made iuds much better now! Or else they wouldn't have put them back on the market!
Also, you gotta realize that there are gonna be side effects to every single form of birth control out there! You can die taking the pill, patch, etc...You can have tubal pregnancies after getting your tubes tied, as well!
You're taking a risk no matter what form you decide to use! If you don't want side effects, then quit having sex! That's the only form of birth control that will keep you from getting pg, as well as keep you from unwanted side effects! However, I don't think many people are gonna choose this form of birth control...I for one, am not!
