Anyone else?

Sometimes I see squiggles and it feels like a strobe light going off in my eye. I lose some vision in my peripherals, and I can't see things I'm directly looking at. It's not double vision, and shortly after I get a headache. Not so much a migraine either. This only happens now and then but it scary and sucks when it does. Anyone else have this happen ever? Hasn't happened since my pregnancy!
