Sore muscles!

Alex
I am just about 30 weeks right now with a little girl. I have noticed that if I have a particularly active day my whole body is sore for days after. Yesterday I swept the driveway, raked the yard, and vacuumed out my car. I have been so sore since! I have always been very active, but besides walks and household chores I haven't done much working out during this pregnancy. Does pregnancy cause you to get sore muscles quicker, or am I just really out of shape? Haha
