What to do next?

I found out i’m pregnant today and I’m 22 years old and have no insurance because my dad passed way and I lost every single inch of it...I just found out today and don’t know how many weeks I am. I can’t afford doctors that charge 800 up front for tests and all. Any advice where to go that’s affordable or what to do next? I’m so stressed I really am excited but don’t know the next move. The only place that doesn’t charge up front is the ER and I don’t have an emergency... Where can I go??
