13 weeks and I have been getting terrible migraines all throughout the pregnancy 
It was usually 1 a week and now it’s becoming a daily occurrence. My eye balls are in agony and my head is banging. GP prescribed labetalol a beta blocker but I’m hesitant to take it. My blood pressure is low anyway 60/90 and I’m worried it will get too low. Any suggestions? I’m in bed most the day every day as the pain is so bad.
