Missouri Medicaid

Emily • Married. 5 year old son. 2 year old daughter. Pregnant with our last.
Alright ladies, anyone from missouri have any experience getting on Medicaid? I am currently 4 weeks and 3 days according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a>, and I have an appointment to verify my pregnancy through a blood test on Monday. I know that I have to have it confirmed by a doctor and then I can apply for Medicaid. My question is how long does it usually take to get approved? I'm so anxious to go to the OB!! We lost my maternity insurance when my husband switched jobs and we can't afford prenatal care without Medicaid. Just wondering how long it will take :)
