Stretching feeling in growin..

lukesbtb

Ok so it has been three years since I was preg with DD so forgive me if this is a "newbie question". I am 12 weeks now but I feel like my growin area is already stretching/spreading. It feels like a pulled muscle in the area at times. I remember this feeling alot towards the end of my first pregancy as I was nearing labor. Is this normal or too early?
