Shortness of breath, 19 weeks

Ambre
Is anyone else having shortness of breath? Just walking to the bathroom or out to my car I get so out of breath and have to lie down. Sometimes if I'm out shopping I will also get really dizzy, my hands will go numb and I get really nauseous. I have to do 30 hours of interning next month and I'm so worried I won't be able to make it to the building.
