hi ... I am 23 years old and 35 weeks pregnant with my 3rd child, yesterday I had an episode, I was feeling well but all of a sudden I felt extremely dizzy and lightheaded, I felt extremely weak as well and my right arm started shaking uncontrolably. I was having a hard time breathing as well, all of this lasted for about 2 minutes and got better until all symptoms dissapeared . is this normal or what could it be?
