The only way to prevent pregnancy 100% is by not having sex. An IUD is a good form of birth control, but is not risk free. You should consult a doctor for the best birth control choice for your lifestyle.
Yes, you can get pregnant with an IUD! Even though there are a lot of posts here, no it doesn't happen often. If you find out early and the IUD strings are visible, you can get it taken out with a small increase of the chance of miscarriage in the few weeks after the IUD is removed.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
