I also think the Catholic church has too much interference in that aspect of life. I am a Christian (Protestant), and I see no problem with using The Pill or Condoms. Just be aware of the hormonal changes that could result from using The Pill.
The Catholic Church teaches that birth control is a no-no, but they also teach that you can avoid sex during peak fertility times to avoid having children. Seems to me that's the same goal, just a different method to reaching the goal.
Also, since God is all-powerful, He can certainly get past any measures we take.
