What to do????

People are saying that this Supreme court case didn't change anything reguarding the state law on medical marijuana. So this means that I'm still legal to grow my meds right? I don't want to get arrested and thrown in jail for growing my own medicinal marijuana. Could a cop come in my house because he smelled the marijuana? If I was at or under my state limit can he still arrest me? And if he can arrest me what would happen? Would I go to jail under federal law or what???? I'm just needing to know because I currently have five flowering females going. I thought I was protected under state law. Can state officers arrest me for growing even though I have my card and everything? I guess I'm kinda trippin but I don't want to go to jail for any reason.....
