headaches blurred vision

I have had a bad headache since yesterday. Last night from around teatime, I got blurred vision. Which I can only describe as a sparkly zigzag line. I went to sleep and when I woke the line had gone but my eyes and head hurt. Today for the majority it has been my head that is sore but now my eyes are hurting again when I move them (no blurred vision this time) I don't want to look at light too long. I'm 17 weeks pregnant. Anything anyone can recommend?
