Yes, light or moderate cramping is completely normal during early pregnancy. Cramping happens because your body is undergoing changes. This is due to the uterus expanding, causing the ligaments and muscles that support it to stretch.
But if you ever feel concerned about the pain you are feeling, contact your doctor right away it never hurts to get a doctor's opinion, and never wait to call the doctor even if you think it's a silly question or concern. Rather be safe than sorry.
I hope this helps :)
