33 Weeks - Extremely out of breath

Brittany • Had our little boy, Huxley, January 3rd 2017. 😍 Not pregnant again, contrary to what my current status on here says...just keeping track of my BFF’s pregnancy ☺️
I'm 33 weeks and have been EXTREMELY out of breath the past two days. I'm not talking the normal amount (have had that for weeks). I constantly feel like I'm going to pass out and sometimes start seeing stars/fuzziness. 
I have very low blood pressure naturally, and my entire pregnancy it has been the exact same every visit - 100/60...wondering if that has something to do with it.
Anyone else having the same problem at 33 weeks?
