18 and pregnant? Help please!

So I just recently found out I’m pregnant and I had a few questions...

Do I just call my usual family doctor and ask for a prenatal appointment?

If I do go to my family doctor, she can’t tell anyone I’m pregnant right? My mom goes to her and so do my brothers and i would be heartbroken if I couldn’t tell them myself.

I’ve never been to an obgyn so do I just ask for referrals while I’m at my prenatal?

Thank you in advance for the advice! I sure need it ♥️😅
