Pregnant and no insurance

I am 15 weeks pregnant and I applied for Medicaid but its been 6 weeks and I haven't heard anything about my application. Tried to call my case manager for follow up but she didnt answer and I just left a voicemail. Now I am worried, what if I was denied Medicaid? my husband and i cant afford ob visits, ultrasounds, delivery costs, etc. I Live in Illinois btw. Is there anybody here who applied medicaid, someone pls tell me how long will it take before i hear anything from them? thank you.
