Short of breath?

💜sherry💜Due:4/7/18 with my 2nd💜

Anyone else feeling out if breath? These last couple days have been miserable for me. Any steps or walks to the car put me on my butt. The same steps I've been taking for the last 13 yrs with no problems. I am overweight but stay pretty active. I don't remember feeling this with my 1st pregnancy.
