Ocular Migraines

I am 24 weeks pregnant and have been getting ocular migraines every 3 days for the past week and a half or so. I used to get them a lot when I was on the birth control pill, so I know it's all hormone related. I get the aura that lasts for 30-40 minutes and then sometimes I get a headache and sometimes I don't. Just curious to see if any other pregnant ladies have been dealing with this on a regular basis also.
