OBGYN Appointments?

Hi guys!

Recently pregnant. I went and confirmed my pregnancy at a women’s clinic when I found out at home. They did the test and gave me a “proof of pregnancy”. At the time, I didn’t know what for until my mom told me it’s for insurance purposes or whatever. Then it hit me that I recently turned 26 and was dropped from my moms insurance 🙃 because I was frantic, I applied for Medicaid with my plan as Amerigroup and was approved. I have a whole list of places who accept this insurance. The issue I’m running into is that when I call offices to make appointments, they say they DONT accept Medicaid but should I be asking instead if they accept Amerigroup since that’s my actual plan? I’m so confused and have never done this before but trying to get insurance through mine or my husbands work would’ve taken months and I’m coming up on when my ultrasound is supposed to be and would like to find an OB home by then. Please advise me!!! I’m lost!

And if it helps, I live in Texas 😭
