Yes cramps are normal in the beginning. But as everyone here said if you feel your cramps are more severe, then you should get it checked. You should have your prenatal visit anytime now, if not get it checked by your OB/GYN
I got a lot of cramps in the first 10 weeks and was so worried, but was just everything stretching to make room for my baby to grow. But I do agree that if you are worried then it's always best to get checked out and certainly doesn't hurt to ask advice
Some women do experience cramping in the earlier stages of pregnancy, but if they're quite painful, it doesn't hurt to get checked.
