All birth control has failure rates. There is no such thing as ideal birth control - but you have an array to choose from:
- go back to condoms, if your partner is ok with it
- you can enhance the efficiency of condoms by using a second barrier method such as a cervical cap or spermicide at the same time
- read up about the copper IUD (Paraguard) it might not give you the same side effects as Mirena, which contains hormones
- natural family planning (in combination with condoms)
- Implanon
Speak to your doctor about the different options and what might work for you, given your medical history.
Good luck!
