So clearly this is a question for my OB who I will see on Thursday, but I'm wondering what your experiences were with contractions. Every time I swim, have sex, or just walk around the block, my belly tightens up for a couple of minutes in what I assume is a contraction. It doesn't hurt, but it feels weird and it makes me want to lie down and rest. I guess I don't really know what I'm feeling and it seems so early to feel contractions. Did you have similar experiences?
