Roe vs Wade....? Question

I don't really know a whole lot about it, but I know that abortion is now banned in a lot of states. I am in Missouri, and abortion is now banned here. Now, that doesn't really bother me unless it's because someone was raped, but my question has to do with miscarriages. I have had three. It's hard for me to even get pregnant, and then when I do, it's hard to keep it. Could I get in trouble and be put in jail if I have a miscarriage? I read last night that jail time is between 5 and 15 years. My fiance and I are trying for baby number 3, but I'm now scared to continue because I don't want to end up in prison for my body failing to hold a pregnancy. I have a 9 year old and a 4 year old, and my nerves are kinda shot about it.
