Numb face, Tunnel vision, vomiting

Ab
I'd love to hear if anyone else has dealt with this problem. Just called the dr and left a message on the nurses line but I'm so anxious to know if anyone else is dealing with this. . 
Out of the blue my face will go numb, I'll feel really nauseous, and I'll have tunnel vision like I'm going to pass out. I've been dealing with that for a couple of weeks now but it has progressed to throwing up right after the tunnel vision. The last appointment I went to I told them about the feeling of almost passing out and they did a blood pressure test of me laying, sitting, and standing. They said that I have very low blood pressure - 87/59. And that I just need to not stand quickly so I won't black out. I'm not dealing with morning sickness anymore so it's not that. I'm 15 w pregnant. 
TIA for the helpful insights!
