Migraine or something else?

So I’ve had bad headaches/migraines since I was was a toddler, I can remember just grabbing g my head and screaming as a little kid then throwing up because the pain was so bad. I had many tests done throughout my life and every doctor and specialist said I was likely just experiencing migraines. I’ve been noticing a lot lately that any flickering light, sun reflection into my eye, flashing of sun through the trees when driving, scrolling through my phone etc. causes my right eye to hurt and feel weird causing my head to hurt really bad but only on the right side, I start to feel really nauseous like I’m going to be sick and I feel a little confused. The feeling sticks around for a while too so I have to be careful with screens and lights. But the headaches come on instantly. Has anyone else experienced this? Is it just a migraine or soMething else? I know my dad suffered from epilepsy but isn’t in my life and I have not seen him since I was a child so I can’t really ask him about it.
