Terrified..

I'm absolutely terrified. For 30 minutes straight, I could not pronounce words that I read and I could barely speak out loud. It's like I completely forgot how to say words or spell words. I would pronounce simple words wrong and could not think of how to say them. I could not type out words either, I literally didn't know how anymore.........The left side of my head is also pounding behind my eye and on my forehead. I'm 15 weeks pregnant but I don't think this is a pregnancy symptom at all!!!!!! I'm only 20 years old, it's impossible to be a stroke right!? I'm literally terrified. It has slowly gotten better but I'm scared! Is this even normal?! It's basically like I completely forgot how to talk and spell for a while! It's 2 am & I do not feel like sitting in the waiting room of the hospital & I sure don't want a hospital bill at all but my gosh, this is insane!!!
