Re your So What Happened: There is nothing "ha ha" about your situation. Maybe one day in the future you can be honest with yourself and realize that the reason 16 year olds aren't supposed to get pregnant is because children shouldn't be having children. The poster who tells you to consider adoption is giving you good advice.
Regardless of what the poster who calls people on this site self-righteous thinks, it's not our job to be supportive of things that are WRONG. It is wrong for children to get pregnant. It is wrong for an adult to get a child pregnant. Your sister is older than you, but neither of you should be pregnant. And if CPS is looking into it, it means that they are worried that a family member did this or an adult. The reason the ONE poster here thinks that we are supposed to tell you that this is okay is because she thinks people are always supposed to agree with selfish and self-serving rants. How irresponsible to agree with a 16 year old being pregnant in your circumstances...

G., you're expecting an awful lot for people not to judge you. Do you really think that the world isn't a judging place when a child gets pregnant?
You probably think you aren't a child. Just the fact that you are letting the father of this child off the hook by not getting him "involved" shows that you are still a child.
You had BETTER have a DNA test done after the baby comes to establish paternity. You had BETTER ask a family lawyer what happens if you don't name the baby's father on the birth certificate in your state. You had BETTER have all your ducks in a row legally when this guy stops giving you child support money.
If you don't do this, you won't deserve to be a mother to this child. The reason is that letting this man off the hook means that you care more about HIM than this baby.
As far as you and your sister both being pregnant is concerned, it's big warning bells to CPS, as it should be.
