Running while pregnant? I've been a runner up until my pregnancy. Once I became pregnant morning sickness kept me out for awhile. I'm finally getting out of my first trimester and feeling a lot more energetic. I laced up and ran yesterday but I could barely make 3 miles at a 12 min pace. Keep in mind usually I run 8-10 miles at a 10 min pace. It was completely discouraging to have such a hard time doing something that I love. Any advice or similar experiences?
