Did you experience more discomfort earlier in your subsequent pregnancy?

Besides getting bigger much faster in my 2nd pregnancy, I also already feel VERY pregnant, even though I'm just 17 weeks. I feel like I can't walk very fast already, and I feel discomfort when I try to. For about an hour this morning, I had a fairly strong pain on my right side at the bottom of my belly. I almost feel like I need to wear some kind of support band.

Have I just forgotten how uncomfortable I was the first time around? Or am I probably experiencing more discomfort from the scarring from my c-section?
