Aura Migraine

I just experienced my first aura migraine. It was so scary I thought I was going blind. At first I thought it was just a blind spot from the light and then it turned into a kaleidoscope of colors and I couldn't see and then it went away and I got a headache. I'm 4 weeks postpartum and a FTM so I've been under a lot of stress and very sleep deprived. I'm just wondering if I'm going to get them more frequently now that I've gotten it? Is there anything I can do??? Should I speak to a doctor?
