The whole thing of the twin belly (and how early it gets here) amazed me the whole time. I don't know when I had to start grabbing/supporting my belly, but I remember how I kept being amazed that my back was "already" hurting like crazy from it.
I did end up getting a belt, and learning how to tuck my pelvis/do a pelvic tilt while sitting anyplace, especially in the car. It already was getting really problematic before 20 weeks, that's for sure. (And our perinatologists' office was an hour's drive away, so I had to figure out some way to survive on those drives every time we went for another ultrasound.)
The belly pictures are getting to me. (And making me want to dig out my "term" photos to add to the "this is where it's all heading" data already in this thread!
) Now you all have me wondering how big you are at 15 weeks, etc. I have a pic of my 20 week belly somewhere. I think it is bigger than a typical 20 week pregnant belly. Give you something to compare to!
I would have to look back over my written record of complaints to know when I was bothered by what, but I do remember that I felt the same pulling and stretching/tightness pain that plagued me late in my first pregnancy, and it was much earlier. I did not feel it as much in the 3rd trimester (compared to what I'd felt around that time in the first pregnancy.) I am trying to remember now if I had the pulling/stretching pain again with the twins after I finally surpassed the belly size I'd reached at full-term the first time (my singleton was born at 41 weeks), and I think I remember that the "growing" got hard again after a certain threshhold, but seriously most of my complaints were about other parts of my body. My back, my pelvis....The belly hurting (skin pain) was mostly earlier. For whatever reason!
