Free Provillus Review

I hate to put my personal business on the internet but I need some advice! My fiance’ has 2 sons, one is biologically mine, the other is my step son. She has been on and off of the pill, the patch and Depo Provera for years. They all make her sick with irregular bleeding, nausea, yeast infections and hair loss. We don’t need anymore kids right now, though. I don’t mind the condoms but she hates them. And sometimes she doesn’t wanna use her diaphragm with spermicide either. What can I do ( besides pulling out) so that we don’t get pregnant again? And please, no disrespectful or sarcastic answers.
