ocular migraines during pregnancy?

Jenn
I'm pregnant with my first baby and am only 9 weeks into my first trimester.  A couple days ago, I had an ocular migraine and then today I had another one. I used to get them a lot about 15 years ago when I was a teenager but haven't experienced them since. Was wondering if anyone else gets them during pregnancy?  My blood pressure has been normal, so I'm not thinking it's a pre-clam thing. Thanks everyone!
