Has anyone else experienced Ocular Migraines, since being pregnant? I do not get any pain except after the visual disturbances have gone. Then I just get what seems like a dull headache. My visual disturbances are like if someone shined a flashlight in my eyes or he flash of a camera, than the weird zigzag anomaly appears in one of my eyes, I can even see it when I close my eyes, and it flashes with light. Anyone else experience this? I have never had Migraines before.
