Hi D.,
Congratulations on your pregnancy and, yes, I felt this during both of my pregnancies. Not only is your skin stretching, but your abdominal muscles and ligaments surrounding your pelvis are stretcing and pulling.
As a mom, preinatal fitness specialist and founder of Maternal Dance, I recently released RHYTHM FOR LIFE - The Prenatal Belly Dance Workout DVD. The chapter called Relax & Rejuvenate is 15 minutes of yoga therapy, stretching and hip opening exercises to ease the tightness and pulling you describe as this is a very common symptom for moms-to-be. Having said this, always run these things by your health care provider.
You may go to my website to check out info about the DVD and upcoming classes/workshops. The Prenatal Belly Dance Workout DVD is also available on the March of Dimes online catalog, http://www.marchofdimes.com/catalog/product.aspx?producti...
and Amazon.com.
Please don't hesitate to contact me with any questions. For more info visit http://www.maternaldance.com or call ###-###-####
