5 weeks 2 days &' cramping

I'm currently 5 weeks and 2 days and I've been cramping almost everyday . It's only mild cramping, but this is my first pregnancy & im just really worried and hoping everything is fine. The cramps come out of no where at times. They feel almost like my period is coming on. My mom said she didn't have any cramping while she was pregnant. I just wanted to know if this is normal or should I be worried.
