I got cramps & sharp pains like that around week nine, the doctor checked it he said it was normal but it got worse so he thought i was miscarrying. Had an ultra sound done & i had a burst cyst on my left ovary. Most painful thing I've ever experienced. I wouldn't have checked it out if my mother hadn't pushed me to though so i guess i owe her one. X)
Anyway, hope your feeling better. (:
