First Time Using BC

Hello! I recently signed up for NuRx and they prescribed me Aviane. I’ve never used birth control, and am pretty active in the gym. Has anyone used this before? What are your thoughts? I haven’t started it yet. I’m terrified of gaining weight and getting acne. I have migraines due to a concussion in 2016, so I’m worried about it possibly triggering more. I’m getting married in August and do not plan to get pregnant for about 2-3 years minimum!
