High Blood Pressure During Pregnancy

B
Today I had my first appointment & they told me there's a chance I might have high blood pressure they took my pressure about two times & they both came back the same; 
How can I get rid of it? I want to be the healthiest i can be for my baby. 😣 I'm not "obese" & I don't really eat unhealthy I'm kinda unsure why I could even have it.
