Hey Julie, You will get a lot of posts on here with people who had very negative and bad experiences.

The injection is called Depo Provera, or Depo Ralavera (same thing) and yes you get an injection every 12 weeks.

I thought it was heaven! I never got any bleeding and no side effects.

However, it did take me 24 months to conceive, and I dont know if that is due to the injections, PCOS, My Dh's sperm or all of the above.

If you are almost certain you dont want any kids, then you may aswell give it a shot
