Cramping/gas pains

Katlin
I'm only 3w 6d along. The last few days I've been having on and off cramping, which has been pretty mild I suppose. But I've been HAving sharp , jabbing pains in my lower right side. I've had no bleeding and my levels have been doubling like they should be. I'm just wondering if anyone else is experiencing it or has experienced it??? This is my first pregnancy so I guess I need some peace of mind. Thanks!
