Ling cautious about pregnancy

U.S. journalist Lisa Ling said she's being cautious about her current pregnancy after suffering a miscarriage in 2010. The "Our America" host told "Access Hollywood Live" she feels lucky because she has felt "completely normal" during the first five months of this pregnancy. "Other than the fact that I feel like I'm getting this big gut, I didn't have any morning sickness or anything," she said Friday. Ling, 39, said she's being cautious with her diet and exercise. "I used to do extremely rigorous Bikram yoga in 110 degrees and I would go on these long jogs. So, I'm trying to temper it a little bit. I'm now just doing stairs up and down, which is great to do at hotels," she said. Ling and husband Paul Song are expecting a daughter, People magazine reported.
