nym....you are 8wks right??
im 7 weeks and i am really having alot of pelvic and abdominal pain. : in my pelvic area its mostly in the back on my ilial-scacral joints (either side of the lower spine) and ive been getting shooting pain in my cervical region. also i can feel the round ligaments of my uterus stretching (that low down pain i think your discribing)
ive noticed that the pain gets worse with each subsiquent preg. ugh!!
..I've been having a lot of abdominal pain that makes me think it might be cramping (and thus get panicky) but no spotting or anything, then I realize, its just trapped gas and after a while I'll let it out (TMI I Know) and feel much better.
