Insurance

So I'm 18 years old, I will be 19 in two weeks. This means I am currently still on my parents Medicaid plan. I'm in Nebraska where at 19 I am a legal adult. So white health care doesn't tell my parents I'm pregnant, will the insurance tell them before I can? I'm in college and will be taking myself to the appointments, I can also set them up myself. But will my parents able to see pregnancy test results/ ultrasound results or whatever is covered in the first one or two appointments? I'm just wondering, I'm sure they can see that they ran one, although maybe not, but cam they see the results/ are they notified about it right away?
