If you have done your DNA test through the State of Missouri, they usually pay for the DNA testing. If they will not, the biological Father and Mother generally have an obligation to pay the bill. If you are unable, you will probably have to have your attorney bring this issue up to your Judge.
I would also suggest talking to a family law attorney and get the paperwork started. Please remember that a guardianship will allow you to have rights with the unborn child. It does not terminate your daughter's or the father's rights.
In the State of Missouri, paternity can be established through a court order that establishes paternity, child custody and child support. Child Support can be estabished through a separate action through Child Support Enforcement. Do you have an order from a Circuit Judge? If so that is the one you need to be following. If you do not have a court order, then you as the mother are presumed to have sole legal and physical custody of your son.
In the State of Missouri, you have the right to a default divorce. You can personally serve him by sheriff or process server. Then wait thirty days.

Or did you pay it through a bail bondsman? If it was through the prosecutor or DCSE it is likely the money would go for the back support.
Barbara, It sounds like you need a lot more information. you need to leave another message to the attorney. The contact the courthouse where your divorce is filed and see if the attorney has withdrawn or if you have an upcoming court date. It could be that the court clerk could give the information that could help you move forward. If you and your ex are still on good terms, the bank can sometimes prepare a form for you both to sign so you can buy your home.
You did not mention in your question about how old your daughter is now. I think it is very important that you have a parenting plan. You need a legal document that spells out who covers medical and that you need a card.
You need to contact a family law attorney immediately. If your rights were terminated you will have a lot to do to reestablish contact with your children. If this is a well known scandal then you will have that to work with in your favor.
