Aura headache

So a few days ago I had an aura headache that completely blurred my vision on my left eye for about ten minutes. Back in august I had a similar headache that was followed by an intensely painful migraine. This time it wasn’t followed by a migraine but numbness that moved across the left side of my face and my left hand to upper arm. The numbness didn’t last but about a few minutes but it was scary. I am almost 37 weeks and I was wondering if any one else has experienced this. I did check my blood pressure and sugar during this attack and they were in normal ranges.
