According to the hundreds of threads about this, some of them right below your own, I'd say it's normal. And a question for your doctor if you're worried.
Cramping is normal..... Not that it makes it any less nerve wracking, but from what I remember of the one pregnancy I've carried through the first trimester I had continued cramping throughout the first 14 weeks or so. I guess it's from uterus growing? Or the horrific gas lol. I wish the cramping would stop though, not only is it making me hella nervous, but the whole point of not having a dang period is to NOT have cramps....that's why I was on an IUD for & years!
