Baby Aspirin?

Had my first official appointment today and my doctor is recommending I take a baby aspirin daily due to my BMI making me a high risk for high blood pressure. I’m in perfect healthy other than being overweight and have never had any history of high BP. Has anyone ever had their dr suggest this? When I research it I’m finding conflicting information and I’m really hesitant to take anything when pregnant. I’ve been eating healthy since I found out I was pregnant and have actually lost a few pounds.
