Am I playing Russian roulette on getting pregnant? - russian bare

My friend and I love the feeling of bare skin during sex. Thus, we found it on the counter. It is a pill that is used, and wait at least 10 minutes. This prevents a spermicide and that sperm by creating a barrier-foam, unable to enter the egg. No one I know has used such a thing. Has anyone used this or if it is good or not? I do not want to get pregnant
