Is this normal?

I am in my 6th week and having sharp cramping every night. It occurs daily between 12-1 while I am sleeping. For about 5-10 minutes i feel sharp pain in my lower abdomen which gets eases out after I pass a bowel. Please let me know if its normal? I am concerned because of the pattern.

I also have very mild cramping sometimes during day on both sides of my vagina.
